The Fabspeed Porsche 964 Carrera RSR Header Muffler Kit is a comprehensive performance exhaust system designed to transform the exhaust flow, sound and character of the air-cooled Porsche 964.
Fits:
- Porsche 964 (911) C2 1989-94
- Porsche 964 (911) C4 1989-94
Inspired by Porsche RSR motorsport exhaust architecture, the system replaces key restrictive factory exhaust components with equal-length RSR-style headers, high-velocity 3-into-1 merge collectors and a dual-outlet performance muffler system.
The result is a freer-flowing exhaust path designed to improve engine breathing, increase horsepower and torque potential, reduce weight and deliver a significantly louder and more aggressive air-cooled flat-six exhaust note.
What This Product Does:
The exhaust system has the important job of carrying combustion gases away from the engine while controlling exhaust flow, noise and, depending on the configuration, emissions.
On a performance engine, the design of the headers, collectors and mufflers can significantly influence how efficiently exhaust gases leave the cylinders.

- Porsche 911 1978-1983 3.0L / SC
- Porsche 911 1984-1986 3.2L
- Porsche 911 1987-1989 3.2L G50
The Fabspeed Porsche 911 Carrera Sport Cat is a high-flow catalytic converter designed as a direct bolt-on replacement for the heavy and restrictive factory catalyst fitted to classic Porsche 911 Carrera models from 1976–1989.
Fits:
- Porsche 911 1976-1977 2.7L / 1976-77 3.0 Carrera
- Porsche 911 1978-1983 3.0L / SC
- Porsche 911 1984-1986 3.2L
- Porsche 911 1987-1989 3.2L G50
Featuring a 300-cell high-flow catalytic converter and mandrel-bent T304L stainless-steel construction, the Sport Cat is designed to reduce exhaust restriction while retaining catalytic exhaust-gas treatment.
Compared with the original catalytic converter, the Fabspeed Sport Cat provides improved exhaust flow, sharper throttle response, reduced weight and a slightly stronger air-cooled flat-six exhaust note.
What This Product Does:
The catalytic converter is part of the vehicle's exhaust and emissions-control system.
Exhaust gases produced during combustion contain pollutants that pass through the catalyst before leaving the exhaust system. The catalytic converter uses its internal catalyst substrate to convert harmful exhaust compounds into less harmful emissions.
The Fabspeed Sport Cat performs this basic catalytic function while using a higher-flow design intended to create less exhaust restriction than the original factory converter.
It is designed to provide:
- Catalytic exhaust-gas treatment
- Improved exhaust flow
- Reduced exhaust backpressure
- Improved throttle response
- Reduced exhaust-system weight
- Slightly increased horsepower and torque
- A sportier exhaust tone
- A modern replacement for an ageing original catalyst
300-Cell High-Flow Catalyst:
- The Sport Cat uses a 300-cell high-flow catalytic converter.
- The catalyst contains a structured internal substrate that provides the surface required for catalytic reactions while allowing exhaust gases to pass through the system.
- Compared with an older and more restrictive factory catalyst, the high-flow design is intended to reduce resistance to exhaust-gas movement.
- This can help the engine breathe more efficiently while retaining a catalytic converter in the exhaust system.
Performance Benefits:
Fabspeed reports gains of approximately:
Wheel Horsepower: +2 WHP
Torque: +2 ft-lb
Weight Reduction: Approx. 9 lb / 4.1 kg
The primary performance benefit is reduced exhaust restriction and improved throttle response rather than a dramatic increase in peak horsepower.
These are manufacturer-reported figures from specific testing and should not be considered guaranteed results for every vehicle.
Actual performance can vary depending on:
- Engine condition
- Engine specification
- Existing exhaust system
- Intake modifications
- Fuel and ignition condition
- Engine tuning
- Fuel quality
- Ambient conditions
- Testing equipment and procedure
Why Upgrading Matters:
The original catalytic converter does not necessarily need to have failed before a Sport Cat is installed.
The Fabspeed unit can also be selected as a performance exhaust upgrade.
Potential benefits include:
- 300-cell high-flow catalyst
- Reduced exhaust restriction
- Improved throttle response
- Slight horsepower and torque improvement
- Approx. 9 lb weight saving
- Sportier exhaust tone
- T304L stainless-steel construction
- Integrated O2 sensor bung
- Direct bolt-on installation
- No cutting or welding required
This makes the Sport Cat particularly relevant for owners who want a freer-flowing catalytic exhaust configuration rather than using a completely catless bypass pipe.

- Porsche 992.2 GT3 2025>>
The Silver Rocket DRS-2 Motorsport Wing and 4.3x3.0 Riser Kit is a combined rear aerodynamic package developed for Porsche 992.1 and 992.2 GT3 models. It pairs a dry carbon fibre wing with CC-1 composite risers that move the aerofoil 4.3 inches higher and 3.0 inches rearward.
Fits:
Porsche 992.1 GT3 4.0L / 2021-24
Porsche 992.2 GT3 2025>>
What This Product Does
The package changes the position and profile of the rear wing to provide a wider range of aerodynamic adjustment. The raised, rearward location is intended to let the aerofoil produce equivalent loading at a lower angle of attack, while also improving the view through the rear window. Its six-position adjustment system enables the rear aerodynamic setting to be configured around the vehicle and its intended use.
Functions
- Manages airflow across the rear of the vehicle
- Provides six selectable angle-of-attack positions
- Raises the wing by 4.3 inches and moves it rearward by 3.0 inches
- Allows rear aerodynamic loading to be adjusted
- Improves rearward visibility compared with the standard wing position
- Creates a Cup car-influenced rear profile
Technical Details
- Wing manufactured from aerospace-grade dry carbon fibre
- CFD-developed wing section with an integrated Gurney flap
- Full carbon frame structure replaces conventional aluminium internal framing
- Six wing settings compared with four positions on the factory 992 GT3 system
- CC-1 carbon composite risers with an OEM-style aluminium-textured surface
- Risers are manufacturer-rated to withstand up to 600 kg of aerodynamic load
SilverRocket states that its CC-1 composite is four times stronger and 48% lighter than aluminium. The risers use the original mounting arrangement without requiring additional drilling, while the wing features high-gloss exposed carbon designed to coordinate with factory Weissach Package carbon components. The DRS-2 endplate profile takes styling cues from the Porsche 935 “Moby Dick”.
At its maximum setting, Silver Rocket reports that the DRS-2 wing produces 75% more downforce than the original 992 GT3 wing, with a 14.3% increase in drag. Positions one to four can be aligned with the corresponding factory wing settings as an initial setup reference, while positions five and six extend the available adjustment range.
Symptoms of Fault
- Cracking near the aerofoil or riser mounting points
- Wing movement or vibration while driving
- Rattling from loose or worn fasteners
- Carbon fibre delamination or clear-coat deterioration
- Uneven positioning across the rear bodywork
- Contact between the wing assembly and adjacent panels
Why Replacement Matters
Loose, damaged or incorrectly positioned aero components can cause vibration, noise and inconsistent airflow. All mounting points, fasteners and panel clearances should be inspected during installation. Correct alignment and angle selection are particularly important for vehicles used on track, so specialist fitting and aerodynamic setup are recommended.
FAQs
- Is this a universal rear wing?
No. Both components are designed specifically around the Porsche 992.1 and 992.2 GT3 mounting arrangement. - How many adjustment positions does the wing provide?
The DRS-2 has six angle-of-attack settings, extending the adjustment range beyond the four-position factory system. - Does fitting require additional drilling?
The CC-1 risers are designed to use the factory mounting locations without extra holes or complex body modifications. - Should the kit be professionally installed?
Specialist installation is advisable to verify fastener security, wing alignment, panel clearance and the appropriate aerodynamic setting.

Based on the European pre-muffler concept, this component replaces the original catalytic converter with a freer-flowing, resonated exhaust section. The result is reduced exhaust restriction, improved throttle response, reduced weight and a stronger air-cooled flat-six exhaust note.
Unlike a simple straight catalyst bypass pipe, the Fabspeed European Pre-Muffler incorporates a straight-through resonator with stainless-steel wool packing. This helps produce a deeper, more refined performance exhaust tone while reducing the harsh rasp often associated with completely straight-piped exhaust systems.
What This Product Does:
The pre-muffler replaces the factory catalytic converter section of the exhaust system.
Instead of forcing exhaust gases through the restrictive catalyst substrate, the Fabspeed pipe provides a freer-flowing route towards the rear muffler.
This is designed to:
- Reduce exhaust restriction
- Improve exhaust-gas flow
- Reduce backpressure
- Improve throttle response
- Increase horsepower and torque potential
- Reduce exhaust-system weight
- Increase exhaust volume
- Enhance the classic air-cooled flat-six sound
Because the original catalytic converter is removed, the component no longer provides the emissions-treatment function of the factory catalyst.
Resonated European Design:
- Rather than using a completely empty straight pipe, Fabspeed incorporates a straight-through resonator.
- The resonator allows exhaust gases to travel through the system with minimal restriction while controlling some of the undesirable frequencies produced by an unrestricted exhaust.
- Its stainless-steel wool packing helps create a deeper, more purposeful exhaust character without the excessive rasp commonly associated with a basic straight catalyst-delete pipe.
Performance Benefits:
Fabspeed states that the European Pre-Muffler provides 16+ wheel horsepower and 15+ ft-lb of torque, together with significantly improved throttle response.
During Fabspeed DynoJet testing, peak curve gains of up to 21 WHP and 17 ft-lb at approximately 4,500 rpm were recorded, with maximum power increases of approximately 16 WHP and 16 ft-lb.
These are manufacturer-reported figures from a specific test vehicle and should not be considered guaranteed results for every Porsche 911.
Actual performance can vary depending on:
- Engine condition
- Engine specification
- Existing exhaust system
- Intake modifications
- Fuel system condition
- Ignition condition
- Engine tuning
- Fuel quality
- Ambient conditions
- Testing equipment and procedure
Why Upgrading Matters:
This product is primarily a performance exhaust modification, rather than a routine service replacement.
The original catalyst does not need to have failed before the Fabspeed pre-muffler can be installed on a vehicle intended for appropriate competition or off-road use.
Reasons for upgrading include:
- Reduced exhaust restriction
- Improved exhaust flow
- Increased horsepower potential
- Increased torque potential
- Sharper throttle response
- Approx. 8 lb weight reduction
- Stronger air-cooled flat-six sound
- Resonated design to control rasp
- T304L stainless-steel construction
- Straightforward bolt-on installation

The Fabspeed Porsche 964 Carrera Deluxe Oval Style Right-Side Exhaust Tip is a premium stainless-steel replacement and styling upgrade for the factory right-side exhaust outlet.
Fits:
- Porsche 964 (911) C2 1989-94
- Porsche 964 (911) C4 1989-94
Featuring a large 4.5-inch oval outlet, mirror-polished finish and lined-tip construction, it gives the rear of the Porsche 964 a cleaner, sportier and more substantial appearance while retaining an OEM-style fit.
Manufactured from mandrel-bent T304L stainless steel, the tip is designed as a direct bolt-on replacement for the original right-side outlet fitted to the stock 964 secondary rear muffler. It can also be used with a compatible 964 secondary CUP muffler bypass pipe.
What This Product Does:
The exhaust tip forms the visible final outlet of the exhaust system.
Exhaust gases that have passed through the engine, catalytic converter and muffler are discharged to atmosphere through this outlet.
Although an exhaust tip generally has little influence on engine performance by itself, it performs several practical and cosmetic functions.
The Fabspeed Deluxe Oval Tip is designed to:
- Replace the factory right-side exhaust outlet
- Provide a clean and correctly positioned exhaust exit
- Upgrade the rear appearance of the Porsche 964
- Provide a larger, sportier 4.5-inch oval outlet
- Replace a damaged, corroded or deteriorated original tip
- Complement performance exhaust modifications
- Provide durable stainless-steel construction
- Maintain an OEM-style mounting arrangement
4.5 Inch Oval Design:
- The enlarged oval outlet gives the rear of the Porsche 964 a more purposeful appearance while remaining sympathetic to the classic body design.
- Its shape fills the exhaust opening more prominently than the standard outlet and provides a subtle performance-inspired visual upgrade rather than radically altering the character of the vehicle.
Mirror Polished Stainless Steel Finish:
The exhaust tip features a mirror-polished stainless-steel finish.
This creates a high-quality appearance at one of the most visible parts of the exhaust system and complements both standard and modified Porsche 964 vehicles.
Regular cleaning can help remove:
- Exhaust soot
- Carbon deposits
- Road dirt
- Water spotting
- Tar
- Road contamination
Because the component is positioned directly at the exhaust outlet, some discolouration and carbon accumulation are normal during use.
Why Upgrading Matters:
This product does not need to be fitted only when the original tip has failed.
It can also be installed purely as an appearance upgrade.
Reasons for upgrading include:
- Larger 4.5-inch oval outlet
- Sportier rear appearance
- Mirror-polished finish
- T304L stainless-steel construction
- Lined-tip design
- OEM-style precision fitment
- Direct bolt-on installation
- Compatibility with the factory secondary muffler
- Compatibility with suitable secondary CUP muffler bypass systems
It is particularly suited to owners who want to enhance the appearance of their Porsche 964 without making permanent modifications to the rear exhaust system.

911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
What This Product Does
These garnish rails sit along the upper edge of the door cards, between the interior door panels and windows. Rennline reverse engineered the design from an original component to reproduce the shape and mounting arrangement while addressing the distortion commonly found in ageing factory rails.
Functions
- Replaces cracked, faded or distorted upper door garnish rails
- Finishes the junction between each door card and window
- Restores a matching pair of left- and right-hand cabin trims
- Uses an internal metal backing plate to resist warping
Technical Details
- Hand-upholstered in black, OEM-matched leather
- Integrated metal backing plate
- Supplied as one left and one right garnish rail
- Handcrafted in the USA; installation difficulty rated 2 out of 5 by Rennline
Symptoms of Fault
- Leather surfaces that have cracked or faded after prolonged exposure to heat and sunlight
- Garnish rails that have bowed, twisted or lifted away from the door
- Upper door trim that no longer sits evenly beside the window
Why Replacement Matters
Original garnish rails can deteriorate and lose their shape after decades of cabin heat and sun exposure. Replacing both sides together restores a consistent appearance and corrects damaged or warped upper door trim. The integrated metal backing is intended to maintain the rail profile and reduce the tendency to distort.

The Fabspeed Porsche 964 Carrera Primary Muffler Bypass Pipe is a performance exhaust upgrade designed to replace the heavy and restrictive factory centre primary muffler with a lightweight, free-flowing Carrera Cup-style straight pipe.
Fits:
- Porsche 964 (911) C2 1989-94
- Porsche 964 (911) C4 1989-94
Inspired by the exhaust arrangement used on Porsche 964 Carrera Cup competition cars, the bypass pipe reduces exhaust restriction, removes substantial weight from the rear of the vehicle and produces a stronger, more aggressive air-cooled flat-six exhaust note.
Unlike a catalytic-converter bypass pipe, this component is installed after the catalytic converter and does not remove the vehicle's catalyst.
What This Product Does:
The standard Porsche 964 exhaust system uses a primary centre muffler to reduce exhaust noise before gases continue towards the secondary rear muffler.
While effective for noise reduction and refinement, the factory primary muffler adds weight and creates additional restriction in the exhaust path.
The Fabspeed Primary Muffler Bypass Pipe replaces this silencer with a freer-flowing straight pipe.
This is designed to:
- Reduce exhaust restriction
- Improve exhaust-gas flow
- Improve throttle response
- Support increased horsepower
- Reduce rear vehicle weight
- Increase exhaust volume
- Enhance the air-cooled flat-six sound
- Create a Carrera Cup-inspired exhaust configuration
Carrera Cup Style Design:
- The bypass pipe is designed as a replica of the type of primary muffler bypass arrangement used in the Porsche Motorsport 964 Carrera Cup racing programme.
- Rather than forcing exhaust gases through the internal chambers of a conventional silencer, the straight-pipe configuration provides a more direct exhaust route.
- This creates a more performance-oriented exhaust system while retaining the vehicle's catalytic converter and secondary rear muffler when used in the standard configuration.
Performance Benefits:
Fabspeed reports approximately:
Crank Horsepower: +12 HP
Wheel Horsepower: +10 WHP
Weight Reduction: Approx. 25 lb
Fabspeed also reports improved throttle response.
These figures are manufacturer-reported results from specific testing and should not be considered guaranteed output for every Porsche 964.
Actual performance can vary depending on:
- Engine condition
- Vehicle specification
- Existing exhaust components
- Intake modifications
- Engine calibration
- Fuel quality
- Ambient conditions
- Testing equipment and procedure
Why Upgrading Matters:
The Fabspeed Primary Muffler Bypass Pipe is primarily a performance, sound and weight-saving upgrade.
The original centre muffler does not need to have failed before the bypass pipe can be installed.
Reasons for upgrading include:
- Approx. 25 lb rear weight reduction
- Reduced exhaust restriction
- Improved exhaust flow
- Improved throttle response
- Increased horsepower potential
- More aggressive flat-six sound
- Carrera Cup-inspired configuration
- T304L stainless-steel construction
- Straightforward bolt-on installation
It provides a useful option for owners who want a noticeably sportier exhaust without deleting the catalytic converter.
