The Fabspeed XperTune Performance Software is an ECU performance upgrade developed for the Porsche 997.2 Carrera and Carrera S (2009–2012). Designed to optimise the factory engine calibration, the software improves horsepower, torque, throttle response and overall driving characteristics while retaining everyday drivability.
Fits:
- Porsche 997 MKII Carrera C2 3.6L 2009-12
- Porsche 997 MKII Carrera C4 3.6L 2009-12
- Porsche 997 MKII Carrera C2S 3.8L 2009-12
- Porsche 997 MKII Carrera C4S 3.8L 2009-12
Rather than requiring the ECU to be removed and sent away for bench flashing, the XperTune system uses an included handheld tuning device that connects to the vehicle through its OBD-II diagnostic port. The handheld is also connected to a Windows PC during the tuning process, allowing the original vehicle data to be read and a custom Fabspeed calibration to be loaded onto the car.
What This Product Does:
The XperTune software changes the calibration within the vehicle's engine control unit to optimise engine performance.
The factory ECU contains calibration data that determines how the engine responds under different operating conditions. Performance software modifies relevant parameters to make better use of the engine's capabilities.
The upgrade is designed to provide:
- Increased horsepower
- Increased torque
- Improved throttle response
- Sharper engine response
- Improved acceleration
- More responsive driving characteristics
- Calibration tailored to the vehicle's configuration
- Better integration with compatible performance modifications
The objective is not simply to increase peak output, but to improve the way the engine responds throughout normal and performance driving.
How Does The XperTune System Work?
One of the main advantages of the XperTune package is that the ECU does not normally need to be physically removed and mailed away for tuning.
The included handheld device communicates with the vehicle through the OBD-II port.
The tuning process involves:
- Reading the vehicle's original ECU data using the handheld tuner.
- Connecting the handheld device to a compatible Windows computer.
- Sending the original vehicle data and relevant vehicle information to Fabspeed.
- Fabspeed creates a calibration for the vehicle's specific configuration.
- The custom tune file is returned electronically.
- The tune is transferred to the handheld device.
- The handheld is connected to the Porsche and the new calibration is written to the ECU.
This allows the tuning process to be completed without removing the ECU from the vehicle.
Why This Upgrade Matters:
The factory Porsche 997.2 Carrera already offers strong naturally aspirated performance, but ECU calibration provides an opportunity to optimise engine response without making major internal engine modifications.
The Fabspeed XperTune package can provide:
- Increased horsepower and torque
- Improved throttle response
- Sharper acceleration
- More responsive driving characteristics
- Calibration tailored to the vehicle
- Compatibility with suitable performance modifications
- Convenient OBD-II flashing
- No routine requirement to remove and ship the ECU
- Ability to restore the factory ECU calibration
For owners seeking additional performance while retaining the fundamental character of the naturally aspirated 997.2 Carrera, ECU software can be an effective part of a wider performance upgrade package.

As many GT3 owners know, the OEM mufflers are prone to cracking, breaking and blowing out, particularly the titanium mufflers on GT3RS cars. Fabspeed Motorsport Engineers design a GT3 primary muffler replacement that not only fixed that issue but also greatly improved on the OEM design in multiple measurable ways. Using our 30+ years of air and water-cooled experience, we took the valve open tubing to 2.75in / 70mm which is the optimal diameter for GT3 engines to have low restriction but maintain high velocity and high RPM GT3 pitch for the signature GT3 CUP car sound. Then, we implemented our signature investment cast 70mm 2.75" X-Pipe for optimal exhaust scavenging and maximum volumetric efficiency. The X merges the two cylinder banks without creating any restriction in exhaust flow. To maintain the factory muffler’s exhaust note and lack of drone, we mimicked Porsche’s 7 chamber design. This makes for a completely drone free muffler, even when running cat-less race headers! Using GT3 headers with cats or Fabspeed headers with HJS German EPA approved catalytic converters along with Fabspeed GT3 Side Muffler Muffler Bypass Pipes for the ultimate emissions compliant lightweight GT3 exhaust. Fabspeed's GT3 center muffler is guaranteed to NEVER BREAK or fail- and OUTPERFORM any other aftermarket GT3 center muffler. 100% made in house at Fabspeed.
SOUND:
This muffler will have a very similar tone to the OEM muffler, however, it will be a bit louder with PSE turned on. It will also sound a bit smoother and higher pitched thanks to our signature X-pipe.
POWER:
On our 997.1/ 997.2 GT3 and GT3RS test car, paired with our Side Muffler Muffler Bypass Pipes, the Rennsport Muffler picked up an impressive 27 ft/lbs of TQ down low at 3,200 RPM. From 2,900 RPM all the way to 5,700 RPM it picks up =12 horsepower or more, and peak power at the wheels is up from 446 to 454! That’s a gain of over 12 HP at the crank- from simply swapping out the fragile restrictive OEM Porsche 997GT3 to the very latest GT3 RS Titanium OEM factory mufflers. BEST ADVICE- but and install a Fabspeed GT3 center muffler and SAVE you fragile OEM GT3 muffler for Concours shows and restoration. All GT3 OEM mufflers BREAK & EXPLODE when driven long and hard enough.

The Fabspeed Porsche 996/997.1 Carrera GT3 Center Outlet Conversion Tips are a specialist exhaust conversion designed to give compatible Porsche 911 Carrera models the distinctive centre-exit exhaust appearance associated with the GT3.
Fits:
- Porsche 996 GT3 MKI 1999-02
- Porsche 996 GT3 MKII 2003>>
- Porsche 997 MK1 GT3 / GT3 RS 2007-09
Designed for vehicles fitted with a GT3-style rear bumper featuring a centre exhaust opening, the conversion uses extended exhaust outlets to redirect the tailpipes from the Carrera's conventional exhaust location towards the centre of the rear bumper.
The system retains the original side-mounted muffler layout while changing the location of the visible exhaust outlets, providing a motorsport-inspired appearance without requiring the exhaust mufflers themselves to be relocated.
Manufactured from 14–16 gauge T304 stainless steel, the conversion tips are designed for straightforward bolt-on installation without cutting or welding.
What This Product Does:
- The Fabspeed conversion tips change the location at which the Carrera's exhaust outlets appear at the rear of the vehicle.
- A standard Carrera uses exhaust outlets positioned towards the outer sections of the rear bumper.
- When a GT3-style bumper with a centre exhaust opening is installed, the standard exhaust outlet position no longer corresponds with the bumper design.
- The Fabspeed conversion system solves this by extending the exhaust outlets towards the centre of the vehicle.
- This allows the exhaust gases to exit through the central opening in the GT3-style rear bumper while retaining the side-mounted muffler arrangement.
GT3-Inspired Centre Exhaust Apperance:
The main purpose of this product is to provide the distinctive centre-exit exhaust configuration associated with Porsche's motorsport-inspired GT3 models.
The conversion provides:
- GT3-inspired centre exhaust styling
- Correct outlet positioning for a GT3-style rear bumper
- A cleaner rear-bumper conversion
- Motorsport-inspired appearance
- Retention of the Carrera side-muffler layout
- A purpose-designed alternative to custom exhaust fabrication
This is primarily an exhaust routing and styling conversion, rather than a conventional performance component intended to create substantial horsepower gains by itself.
Why Install A Centre Outlet Conversion:
This product is primarily intended for owners converting a Carrera to a GT3-style rear bumper and exhaust appearance.
Reasons for installing the system include:
- GT3-inspired styling
- Centre-exit exhaust conversion
- Correct exhaust positioning for a GT3-style bumper
- Avoiding custom exhaust fabrication
- Retaining the existing side-muffler layout
- Choice of exhaust-tip finishes
- Straightforward bolt-on installation
It provides a purpose-designed solution for completing the rear appearance of a GT3-style Carrera conversion.

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.
