Choose from the following torsion-bar rates: 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm 24 mm, 25 mm or 26 mm.
With sizes ranging from the factory-style 19 mm rate through to the competition-focused 26 mm option, this Sway-A-Way range allows the front suspension to be tailored for standard road use, fast-road driving, track days or dedicated motorsport applications.
Product Information
The classic Porsche 911 uses torsion bars as its suspension springs. As the front suspension moves, the torsion bar twists along its axis and provides the resistance necessary to support and control the vehicle.
Increasing the torsion-bar diameter increases the spring rate, providing greater resistance to suspension movement. This can help reduce front-end dive under braking, limit body roll during cornering and provide a more immediate chassis response.
Manufactured using solid high-strength 4340 alloy steel, Sway-A-Way torsion bars are designed to withstand repeated torsional loading while providing consistent spring characteristics.
Choosing the Correct Torsion Bar Rate
19 mm Solid (OEM Standard Diameter)
The 19 mm torsion bar is the factory-style option within the range and is ideal for owners looking to replace tired original torsion bars while maintaining near-standard suspension characteristics. Note: Engineered as a direct-fit replacement for the front independent suspension.
Recommended for:
• Standard road cars
• Original-specification restorations
• Touring use
• Cars where ride comfort is important
• Owners seeking factory-style front suspension behaviour
This is the natural choice where maintaining the classic Porsche road feel is the priority.
Installation & Setup Notes:
• Indexing & Ride Height: These bars utilize the factory splined ends. Correct indexing (clocking) during installation is critical to achieving the proper stance. Small adjustments at the splines result in significant changes at the wheel.
• Grease: Always apply a high-quality Moly-based or waterproof grease to the splines before sliding the bars into the A-arms and adjustment caps to prevent future seizing and "creaking" during cornering.
• Upgrade Path: If you are preparing your 911 for competitive autocross or track days, consider stepping up to a 21mm or 22mm bar. This 19mm bar is specifically optimized for street comfort and original factory handling dynamics.
20 mm Solid (Performance Upgrade)
The 20 mm torsion bar provides a mild increase in front spring rate compared with the standard 19 mm setup. It offers sharper suspension response and reduced front-end movement without moving too far away from road-oriented ride characteristics.
Spring Rate: Higher than OEM (Approximately 23% stiffer than 19mm bars)
Note: A popular choice for Carrera models looking to sharpen front-end response or for early "long-hood" cars being prepared for rally or fast road use.
Recommended for:
• Fast-road cars
• Mild performance upgrades
• Weekend sports cars
• Uprated road suspension
• Cars using performance dampers and tyres
A good choice for owners wanting a noticeable but relatively restrained suspension upgrade.
Installation & Performance Notes:
• Balanced Handling: When increasing the front bar diameter to 20mm, it is highly recommended to also upgrade the rear torsion bars (typically to 26mm or 27mm) to maintain the 911’s neutral handling balance and prevent induced understeer.
• Spline Maintenance: Thoroughly clean the female splines in the A-arms and adjustment caps. Use a high-pressure waterproof grease on the splines during assembly to prevent "popping" noises and ensure easy adjustment in the future.
• Indexing: Because these bars use the factory spline count, small changes in indexing result in significant ride height shifts. We recommend documenting your original bar's orientation before removal.
21 mm Solid (Performance Upgrade)
The 21 mm torsion bar provides a more significant increase in front spring rate and is well suited to performance-oriented road and occasional track cars. Spring Rate: Stiffer than OEM (Approximately 45–50% stiffer than 19mm bars).
Note: This is a common performance upgrade for Carrera 3.2 and SC models to improve front-end bite and overall chassis responsiveness.
Recommended for:
• Fast-road Porsche 911s
• Road and track-day cars
• Autocross Carrera and SC performance builds
• Cars using uprated dampers
• Modern high-grip tyre packages
The increased rate provides stronger resistance to front suspension compression during braking and cornering.
Installation & Performance Notes:
• Chassis Balance: Upgrading to 21mm front bars typically requires a corresponding upgrade to the rear torsion bars (often to 27mm or 28mm) to maintain the 911's intended handling characteristics and prevent excessive understeer.
• Shock Matching: Due to the significantly increased spring rate, factory comfort shocks will likely be under-damped. For best results, pair these with performance-valved shocks (such as Bilstein Clubman or Koni Sport).
• Indexing: Document your factory bar indexing before removal. Because of the high spring rate, even a one-spline difference in "clocking" will result in a dramatic change in ride height.
22 mm Solid
The 22 mm solid torsion bar moves further toward a track-focused suspension setup. It provides increased front-end support and reduced body movement, making it suitable for cars where handling response is prioritised over standard road comfort. Spring Rate: Stock Equivalent. Note: While 22mm is typically a performance diameter, this SKU is specifically manufactured to provide a factory-style ride quality.
Recommended for:
• Aggressive fast-road use
• Frequent track days
• Autocross
• Lightweight performance cars
• Uprated dampers
• Complementary rear torsion-bar upgrades
Installation & Setup Notes:
• Spline Fitment: These bars utilize the factory-style splined ends. Ensure the female splines in your A-arms and adjustment caps are thoroughly cleaned and free of debris before installation.
• Lubrication: Use a high-quality, high-pressure waterproof grease on the splines during assembly to prevent "popping" or "creaking" and to ensure easy removal in the future.
• Indexing: Because small changes in spline "clocking" result in significant ride height shifts, document your original bar's orientation before removal to simplify the setup of your new stance.
23 mm Solid (Competition Grade)
The 23 mm solid torsion bar is a substantial performance upgrade designed for aggressive road, track and competition applications. It provides considerably greater resistance to front-end dive and body roll than the factory-style 19 mm configuration. Spring Rate: Significantly higher than OEM (Approx. 110–120% stiffer than 19mm bars). Note: Ideal for 911s used in competitive track environments, autocross, or for owners who prefer a very firm, communicative chassis.
Recommended for:
• Track-focused Porsche 911s
• Motorsport-inspired build
• Autocross
• Competition applications
• Cars using performance or competition dampers
• High-grip tyre setup
At this level, the complete front-to-rear suspension balance becomes particularly important.
Installation & Performance Notes:
• Chassis Reinforcement: Because 23mm bars exert significantly more force on the chassis than factory bars, it is highly recommended to inspect—and potentially reinforce—the torsion bar mounting points and A-arm brackets.
• System Balance: To maintain neutral handling, 23mm front bars must be paired with much stiffer rear bars (typically 30mm or 31mm). Failure to balance the rear will result in severe understeer.
• Shock Damping: Standard or even "Sport" street shocks will be insufficient for this spring rate. Competition-valved dampers (such as Bilstein RSR or Custom Valved Koni) are necessary to control the oscillation of a 23mm bar.
• Spline Care: Apply high-pressure waterproof grease to the splines during assembly to prevent "popping" noises and to ensure the bars do not seize in the A-arms.
24 mm Solid
The 24 mm solid front torsion bar provides a high spring rate intended primarily for developed performance and competition suspension packages.
Recommended for:
• Dedicated track cars
• Competition Porsche 911s
• Lightweight race builds
• High-grip tyre applications
• Cars with substantially uprated rear torsion bars
• Competition-valved dampers
This size is most appropriate where chassis control takes priority over road comfort.
25 mm Solid
The 25 mm solid torsion bar is a very high-rate front suspension option aimed at serious motorsport applications.
Recommended for:
• Race-prepared Porsche 911s
• Motorsport builds
• High-downforce or high-grip cars
• Competition suspension systems
• Vehicles with appropriately matched rear spring rates
Professional suspension setup is strongly recommended at this level of spring stiffness.
26 mm Solid
The 26 mm solid torsion bar represents the most aggressive option in this range. Designed for highly developed competition vehicles, it provides extremely high resistance to front suspension movement and should only be used as part of a properly engineered suspension package.
Recommended for:
• Dedicated race cars
• Motorsport applications
• Highly developed track builds
• Very high-grip suspension setups
• Cars using competition-spec dampers
• Vehicles with suitably matched rear torsion-bar rates
For typical road use, one of the smaller sizes will generally provide a more appropriate balance of suspension performance and compliance.
Why Upgrade Front Torsion Bars?
On a classic Porsche 911, the torsion bar performs the same fundamental function as a conventional coil spring. When the suspension moves, the bar twists. The resistance of the bar to this twisting movement determines the effective spring rate.
Increasing the torsion-bar diameter can provide:
• Reduced front-end dive under braking
• Reduced body roll Improved steering response
• Greater suspension control
• More immediate turn-in
• Better support for performance tyres
• Improved chassis response during track driving
• Increased resistance to suspension compression
The larger the solid torsion-bar diameter, the greater the spring rate.
Solid Construction
These torsion bars use a traditional solid construction. Solid torsion bars are an excellent choice for owners who prioritise performance, durability and value over the weight saving provided by tubular alternatives.
Advantages include:
• Proven construction
• High torsional strength
• Consistent spring behaviour
• Excellent durability
• Wide choice of spring rates
• Competitive cost compared with hollow alternatives
• Suitable for road and competition use
For customers primarily focused on achieving a specific spring rate rather than reducing suspension component weight, the solid Sway-A-Way range provides an excellent solution.
4340 Alloy Steel
Sway-A-Way uses high-strength 4340 alloy steel for its Porsche torsion bars. This material is particularly suitable for components subjected to repeated twisting loads because of its combination of strength and fatigue resistance.
The manufacturing process includes:
• High-strength alloy-steel construction
• Precision centreless grinding
• Heat treatment
• Shot peening
• Controlled dimensions
• Protective powder coating
These processes help provide predictable spring characteristics and long-term durability.

SET OF 2, One pair is required per vehicle
Fits:
Porsche 911 1987-1989 3.2L G50
Porsche 911 1978-1989 3.3L Turbo (930)
Always confirm that your vehicle uses the G50 transmission and corresponding rear suspension configuration before ordering.
Available in 26 mm, 27 mm, 28 mm and 29 mm diameters, the range provides several levels of rear suspension stiffness, from a relatively mild fast-road upgrade through to a much firmer track-focused setup.
Increasing the torsion-bar diameter raises the effective spring rate, helping reduce rear suspension movement, body roll and squat during acceleration. This can provide a more controlled and responsive chassis, particularly when combined with suitable front torsion bars, dampers, anti-roll bars and performance tyres.
The solid construction offers a straightforward, durable solution for owners looking to upgrade the suspension without the additional cost associated with lightweight hollow torsion bars.
Available Torsion Bar Rates
26 mm Solid (performance street / light-track upgrade)
The 26 mm solid rear torsion bar is the mildest performance option in this range. It provides increased rear suspension support while remaining particularly suitable for a road-focused Porsche where improved chassis control is wanted without moving directly to a substantially stiffer competition setup.
Recommended for:
• Performance road cars
• Fast-road use
• Mild suspension upgrades
• Uprated dampers
• Cars using modern performance tyres
• Occasional track-day use
Installation & Performance Notes:
• System Balance: Suspension tuning is about ratios. If you increase the rear bar size to 26mm, you should ensure your front torsion bars are matched accordingly (typically paired with 21mm or 22mm front bars) to prevent excessive oversteer.
• Indexing and Ride Height: Setting the ride height on a 911 is done by "clocking" the splines on the torsion bar. Because the 26mm bar is stiffer than stock, the car will sit higher than it did with the factory bars if indexed at the same angle.
• Bushings: This is the perfect time to inspect or replace your rear spring plate bushings. High-performance bars work best when paired with fresh polyurethane or Neatrix bushings to eliminate "stiction."
• Lubrication: Clean the splines thoroughly and apply a generous amount of waterproof, anti-seize grease to both ends of the bar. This prevents the bars from "creaking" and ensures they won't seize in the tube for future adjustments.
27 mm Solid
The 27 mm solid rear torsion bar provides a more noticeable increase in rear spring rate. It is a strong choice for drivers looking for a more responsive chassis while retaining versatility for both road and occasional circuit use.
Recommended for:
• Fast-road Porsche 911s
• Clubsport-style builds
• Road and track-day cars
• Autocross
• Performance suspension packages
• Cars using uprated front torsion bars and dampers
The 27 mm Sway-A-Way bar is specifically positioned as a high-performance rear suspension upgrade for Porsche 911 applications.
Technical Setup & Performance Notes:
• Chassis Balance: A 27mm rear bar is quite stiff. It is almost always paired with 22mm front torsion bars to maintain a neutral handling balance. Pairing 27mm rears with stock small-diameter fronts may result in excessive oversteer (the tail sliding out).
• Damping Requirements: Due to the higher spring rate, you will likely need to upgrade to "Sport" valved dampers (such as Bilstein Clubsport or custom-valved Koni) to control the faster rebound speeds of these bars.
• Ride Quality: While still streetable, the 27mm bar will transmit more road vibration than stock. It is perfect for canyon carving and track use but may feel firm over city potholes.
• Weight Comparison: If choosing the Tubular option, you effectively reduce "unsprung" weight. This allows the suspension to react faster to bumps, keeping the tire in better contact with the pavement compared to a heavier solid bar of the same rate.
28 mm Solid (competition / heavy performance)
The 28 mm solid rear torsion bar moves further toward a dedicated performance suspension setup. The increased spring rate helps provide stronger resistance to suspension compression and body movement during aggressive cornering and acceleration.
Recommended for:
• Aggressive fast-road use
• Regular track days
• Autocross
• Lightweight performance builds
• High-grip tyre packages
• Cars with appropriately matched performance dampers
A 28 mm rear bar should be considered as part of the complete suspension package rather than as an isolated upgrade.
Critical Installation & Performance Notes:
• Chassis Balance: A 28mm rear bar is extremely stiff. To avoid dangerous snap-oversteer, these must be paired with upgraded front torsion bars (typically 23mm or 24mm fronts).
• Damping Requirements: Standard street shocks (like Bilstein HD) will be completely overwhelmed by this spring rate. You must use custom-valved racing dampers with high rebound control to prevent the car from bouncing uncontrollably over bumps.
• Mounting & Bushings: At this performance level, factory rubber bushings will deflect excessively. We highly recommend upgrading to spherical bearings or bronze bushings to ensure the torsion bar can move freely without binding.
• Ride Quality: This setup is very firm. While technically street-legal, it is optimized for smooth race tracks and high-speed canyon carving. You will feel every imperfection in the road surface.
29 mm Solid (full competition grade)
The 29 mm solid rear torsion bar is the stiffest option in this range and is aimed primarily at more serious track and competition-oriented builds.
It provides substantial rear roll stiffness and resistance to acceleration squat, making it suitable for cars where maximum suspension control takes priority over standard road comfort.
The 29 mm solid rear bar is a competition-focused option for highly developed performance applications.
Recommended for:
• Track-focused Porsche 911s
• Competition builds
• Motorsport applications
• High-grip tyre setups
• Lightweight race cars
• Cars using matched competition dampers
• Vehicles with complementary front spring rates
Critical Competition Notes:
• Chassis Balance: A 29mm rear bar is exceptionally rigid. To prevent dangerous snap-oversteer, it is mandatory to pair these with appropriately stiff front bars (typically 23mm to 24mm).
• Damping Requirements: Standard or "Sport" street shocks are completely insufficient for this rate. You must use professional, custom-valved racing dampers with significant rebound control to manage the energy of a 29mm bar.
• Bushings & Bearings: We strongly recommend replacing rubber bushings with spherical bearings or high-durometer bronze bushings. Factory rubber will simply collapse under the forces transmitted by a 29mm bar, leading to unpredictable handling.
• Ride Quality: This setup is not recommended for street use. The ride will be extremely harsh, and the high spring rate can put significant stress on factory chassis mounting points if they are not reinforced.
Why Upgrade the Rear Torsion Bars?
The classic Porsche 911 uses torsion bars as its suspension springs.
Rather than compressing like a conventional coil spring, the torsion bar twists along its axis as the wheel moves through its suspension travel.
Increasing the torsion-bar diameter increases resistance to twisting and therefore raises the suspension spring rate.
Benefits of an appropriately selected larger rear torsion bar can include:
• Reduced body roll
• Reduced rear-end squat during acceleration
• Improved chassis response
• Increased suspension control
• Better support for modern performance tyres
• Improved stability during fast cornering
• More predictable suspension movement on track.
Solid Construction
These Sway-A-Way torsion bars use a conventional solid construction.
Solid torsion bars offer several advantages:
• Simple and proven construction
• Excellent torsional strength
• Consistent spring characteristics
• Durable performance
• Competitive pricing compared with tubular alternatives
• Suitable for both road and competition use
For customers primarily interested in increasing spring rate rather than reducing suspension component weight, the solid-bar range offers an excellent performance solution.

- Porsche 997 MK1 GT3 / GT3 RS 2007-09
The Fabspeed Center Muffler Bypass Pipe is a high-performance replacement for the factory center muffler on 2006–2009 Porsche 997 GT3 and GT3 RS models.
Fits:
- Porsche 997 MK1 GT3 / GT3 RS 2006-09
Designed to replace the original center silencer, the system creates a freer-flowing exhaust path while producing a more aggressive, motorsport-inspired exhaust note. Fabspeed's crossover or “talk-pipe” design blends exhaust gases from the left and right cylinder banks, creating a smoother and more distinctive exhaust sound.
Constructed from 14–16 gauge T304 stainless steel, the bypass pipe is designed to withstand high exhaust temperatures, moisture and repeated heat cycles while reducing weight at the rear of the vehicle.
Fabspeed lists performance gains of approximately 10 hp and 6 lb-ft of torque, together with a 10 lb weight saving compared with the factory center muffler. Actual results can vary depending on vehicle condition and operating conditions.
What This Product Does:
The factory center muffler reduces exhaust noise by routing exhaust gases through an internal silencing structure. While effective at controlling sound, the muffler also adds weight and creates additional restriction in the exhaust path.
The Fabspeed Center Muffler Bypass Pipe replaces this component with a more direct exhaust route.
Its main benefits include:
- Reducing exhaust restriction
- Improving exhaust gas flow
- Reducing weight at the rear of the vehicle
- Producing a louder and more aggressive GT3 exhaust note
- Blending exhaust pulses from both cylinder banks
- Improving throttle response
- Supporting increased horsepower and torque
- Retaining Sport Mode functionality when used with the factory side mufflers
- Replacing the failure-prone original center muffler
The bypass system retains the original side mufflers, allowing the factory Sport Mode exhaust control to remain functional when they are retained.
Symptoms Of Wear Or Failure:
The original GT3 center muffler is exposed to extremely high exhaust temperatures, pressure fluctuations, vibration and repeated heating and cooling cycles.
Fabspeed specifically describes the factory center muffler as failure-prone. It also notes that repeated expansion and contraction of the muffler casing can contribute to metal fatigue and cracking over time.
Common symptoms of a deteriorating center muffler may include:
- Cracks or splits in the muffler casing
- Cracking around welds or seams
- Exhaust gas leaks
- Black soot around cracks or joints
- Blowing or hissing exhaust noises
- Sudden increase in exhaust volume
- Metallic rattling from the center muffler
- Loose or damaged internal components
- Deformation or movement of the muffler casing
- Exhaust fumes around the rear of the vehicle
- Damaged or corroded mounting points
- Abnormal vibration from the exhaust system
- Evidence of fatigue around repeatedly stressed areas
Track use and repeated high-temperature operation can place additional thermal and mechanical stress on the original muffler.
Why Replacement Matters:
- A cracked or damaged center muffler can allow hot exhaust gases to escape before reaching the intended outlets.
- Apart from creating excessive or irregular exhaust noise, leaks may expose surrounding components to additional heat and allow soot to accumulate around the damaged area. Cracks can also continue to propagate as the muffler repeatedly heats, expands and cools.
- Replacing a deteriorated center muffler restores a secure exhaust path and prevents continued deterioration of the damaged component.
- For owners seeking a performance upgrade rather than simply repairing the factory exhaust, the Fabspeed bypass pipe removes the original silencer entirely. This eliminates the factory center muffler as a potential failure point while reducing restriction and rear-mounted weight.

- Fuel-rail spacers are marked for adjustment to long, medium or short Bosch injector formats
- Manifold-side transition is designed for a 42mm bore
Components Not Included
Intake manifolds, rubber joining sleeves, fuel injectors and hose clamps are not supplied with the base adapter kit.
Installation Notes
This component forms part of a custom EFI installation rather than a complete conversion package. Confirm the cylinder-head port diameter, injector length, manifold specification and clearance around the throttle and idle-control components before assembly. Engine-management hardware, fuel delivery components and calibration must be selected for the completed installation.
- Porsche 997 MK1 TURBO 2007-09
The Fabspeed Deluxe Quad-Style Exhaust Tips are premium replacement exhaust outlets designed for the 2006–2009 Porsche 997 Turbo.
Fits:
- Porsche 997 MK1 TURBO 2006-09
Featuring substantial 3.5-inch outlets, these quad-style tips give the rear of the 997 Turbo a more purposeful, performance-inspired appearance while replacing ageing, corroded or damaged original exhaust tips.
Manufactured from high-quality 14–16 gauge T304 stainless steel, the tips are designed to withstand exhaust heat, condensation, road contamination and repeated temperature changes. They are available in polished or satin black ceramic-coated finishes, allowing the appearance of the exhaust to be tailored to the vehicle.
The bolt-on design makes them suitable for use with both factory and compatible aftermarket exhaust systems.
What This Product Does:
Exhaust tips form the visible final section of the exhaust system through which exhaust gases leave the vehicle.
Their main functions include:
- Providing a finished outlet for the exhaust system
- Directing exhaust gases away from the rear of the vehicle
- Replacing damaged, corroded or deteriorated original tips
- Improving the appearance of the rear bumper and exhaust outlets
- Providing a distinctive quad-tip performance look
- Maintaining secure and correctly positioned exhaust outlets
- Offering durable stainless-steel construction for long-term use
- These tips are primarily an appearance, durability and replacement upgrade rather than a major engine-performance modification.
Exhaust tips are continuously exposed to heat, moisture, condensation, exhaust deposits and road debris. Over time, the original outlets can deteriorate.
Common signs that replacement may be required include:
- Rust or visible corrosion
- Pitting in the metal surface
- Permanent staining or severe discolouration
- Peeling or deterioration of the original finish
- Dents or deformation caused by impact
- Scratches or cosmetic damage
- Loose or unstable exhaust tips
- Rattling or vibration while driving
- Cracks around welds or attachment points
- Tips sitting unevenly or incorrectly aligned
- Excessive soot deposits around the connections
- Exhaust tips contacting the bumper or surrounding trim
- Mounting hardware that is heavily corroded or no longer secure
A tip that has become badly corroded around its mounting area may eventually loosen or detach.
Why Replacement Matters:
Damaged or badly deteriorated exhaust tips can affect both the appearance and security of the exhaust outlet.
A loose tip may vibrate or rattle and can move sufficiently to contact the bumper or nearby trim. Continuous contact can damage painted or finished surfaces and place additional stress on the exhaust mounting points.
Heavy corrosion may also weaken the attachment area, increasing the possibility of the tip becoming insecure.
Replacing worn exhaust tips helps restore:
- Correct exhaust outlet positioning
- Secure mounting
- A cleaner rear-end appearance
- Reduced rattling or unwanted movement
- Protection against contact with surrounding trim
- A more consistent and finished appearance
Where the remainder of the exhaust system is still in good condition, replacing the tips also provides a cost-effective way to refresh the appearance of the vehicle without replacing silencers or other major exhaust components.

- Porsche 997 MK1 TURBO 2007-09
The Fabspeed Sport Headers are a high-performance replacement for the factory exhaust manifolds on 2006–2009 Porsche 997 Turbo models.
Fits:
- Porsche 997 MK1 TURBO 2006-09
Designed to improve the flow of exhaust gases from the cylinder heads to the turbochargers, these headers use equal-length primary tubing and high-velocity 3-into-1 merge collectors to create a smoother and less restrictive exhaust path.
They are manufactured from 14–16 gauge CNC mandrel-bent T304L stainless steel, providing excellent resistance to heat, corrosion and repeated thermal cycling.
Fabspeed designed the headers as a direct replacement for the original Porsche headers, making them suitable as both a performance upgrade and a replacement for ageing or damaged factory exhaust manifolds.
What This Product Does:
The exhaust headers collect exhaust gases leaving the engine's cylinders and direct them towards the turbochargers.
On a turbocharged engine, the energy contained in the exhaust gases is used to drive the turbine wheels. Efficient exhaust flow before the turbochargers can therefore influence turbo response, engine breathing and overall performance.
The Fabspeed Sport Headers are designed to:
- Improve exhaust gas flow
- Reduce restriction before the turbochargers
- Improve exhaust scavenging
- Support faster and more responsive turbo operation
- Improve throttle response
- Support increased engine performance
- Provide smoother exhaust flow through equal-length tubing
- Replace ageing factory manifolds with durable stainless-steel components
The 3-into-1 merge collector design brings the exhaust gases from three cylinders together smoothly before they reach each turbocharger, helping minimise turbulence and improve exhaust flow.
Symptoms Of Wear Or Failure:
Factory exhaust manifolds operate under extremely demanding conditions, including very high exhaust temperatures, constant vibration and repeated heating and cooling cycles.
Common symptoms of worn, cracked or leaking exhaust headers include:
- Ticking or tapping noises when the engine is cold
- Blowing or hissing noises from the exhaust manifold area
- Exhaust leaks around the cylinder-head flanges
- Black soot deposits around manifold joints
- Cracks in the manifold or welds
- Warped mounting flanges
- Broken or heavily corroded mounting hardware
- Increased exhaust noise
- Exhaust fumes around the engine compartment
- Reduced throttle response
- Reduced or inconsistent turbo response
- Loss of engine performance
- Increased heat around nearby engine components
Similar symptoms can also be caused by failed exhaust gaskets, loose fasteners or leaks elsewhere in the exhaust system, so the complete assembly should be inspected before replacement.
Why Replacement Matters:
An exhaust header must provide a secure and sealed path for gases travelling from the engine to the turbocharger.
If a header cracks or develops a leaking flange, exhaust gases can escape before reaching the turbocharger. This reduces the exhaust energy available to drive the turbine and may contribute to poorer turbo response and reduced performance.
Escaping exhaust gases can also expose surrounding components to excessive heat and create unwanted noise.
Replacing damaged or deteriorated headers helps restore:
- A properly sealed exhaust path
- Efficient delivery of exhaust gases to the turbochargers
- Consistent turbocharger response
- Correct exhaust flow
- Reduced exhaust leakage
- Improved durability
For owners upgrading rather than repairing, the Fabspeed equal-length design and high-velocity merge collectors are intended to reduce restriction compared with the original headers and improve overall engine response.

- Porsche 997 MK1 TURBO 2007-09
The Fabspeed Supersport Performance Package is a comprehensive performance upgrade designed for the 2006–2009 Porsche 997 Turbo.
Fits:
- Porsche 997 MK1 TURBO 2006-09
Rather than replacing a single component, this package upgrades several key areas of the engine's breathing and exhaust system. It combines a freer-flowing Supersport X-Pipe exhaust, performance headers, Competition Air Intake, Deluxe Quad Style exhaust tips and Fabspeed XperTune Performance Software.
Together, these components are designed to reduce intake and exhaust restrictions, improve exhaust scavenging, enhance turbo response and optimise engine management for the upgraded hardware.
Fabspeed quotes gains of approximately 74 wheel horsepower and 78 ft-lb of torque, although actual results will vary depending on vehicle condition, fuel, specification and operating conditions.
Package Includes:
- Fabspeed 997 Turbo Supersport X-Pipe Exhaust System
- Cat-Bypass Pipes for Race configuration
- Fabspeed 997 Turbo Sport Performance Headers
- Fabspeed Deluxe Quad Style Exhaust Tips
- Fabspeed Competition Air Intake
- Fabspeed XperTune Performance Software
What This Product Does:
The package improves the way air enters the engine, how exhaust gases leave the cylinders and how the engine management system responds to the upgraded hardware.
The Supersport exhaust replaces the heavier and more restrictive factory rear exhaust arrangement with a freer-flowing X-pipe system.
This helps:
- Reduce exhaust restriction
- Improve exhaust gas flow
- Produce a stronger performance exhaust sound
- Allow the turbochargers to operate against a less restrictive exhaust system
- Support increased horsepower and torque
Symptoms Of Wear Or Failure:
Because this package replaces and upgrades several systems, potential symptoms depend on which original component has deteriorated.
Ageing factory exhaust components may show:
- Corrosion or rust
- Cracked exhaust pipes or welds
- Blowing or hissing noises
- Exhaust leaks
- Black soot around leaking joints
- Rattling from silencers or catalytic converters
- Reduced engine or turbo response
- Increased exhaust restriction
- Damaged catalytic converter material
- Check Engine Light relating to catalyst efficiency
- Exhaust fumes around the rear of the vehicle
- Loose or damaged mounting points
Why Replacement / Upgrading Matters:
- The 997 Turbo's engine relies on efficient airflow both before and after the turbochargers.
- Restrictions in the intake system make it harder for the engine and turbochargers to draw in sufficient air, while excessive exhaust restriction can work against efficient evacuation of exhaust gases.
- Ageing catalytic converters, damaged silencers, cracked headers or contaminated filters may therefore affect performance and responsiveness.
- Replacing deteriorated components restores system integrity, while upgrading to freer-flowing components can reduce restriction and allow the engine to operate more efficiently.
- The Fabspeed package goes further by combining the hardware upgrades with ECU calibration designed around the improved airflow characteristics. This creates an integrated package rather than fitting individual performance components independently.
