For late model exhaust brackets
The Fabspeed Lightweight Competition Exhaust System for the 718 4.0L cars was specifically designed to be the lightest, best performing exhaust possible. Our design process started with 3D scanning the entire exhaust system using our CREAFORM 700 Handscan so that we could make a complete Solidworks 3D model of the exhaust. We then designed the exhaust and fixtures using that model so that the exhaust fit perfectly to OEM standards. After multiple revisions for sound and dyno testing we settled on 2.5' 63.5mm tubing with a crossover tube to increase exhaust scavenging and reduce drone. The flanges are thick 304 stainless steel that we CAD designed to perfectly match the OEM flanges and reuse the factory metal gaskets.
SOUND: This systems deletes the factory PSE valves so it always provides an aggressive snarl no matter what RPM you're at. This system will be a significant increase in volume, with minimal cabin drone in the lower rpm region.
FEATURES:
• Fits all 718 Cayman GT4 / GTS / Spyder Cars 2020+
For late model exhaust brackets
• Saves 17lbs / 7.3kg over the factory PSE muffler
• Constructed from high-quality 14-16ga CNC mandrel-bent T304L stainless steel for optimum flow and maximum durability
• Crossover tube helps with exhaust scavenging and reduces drone

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.

Replacing the restrictive factory mufflers with freer-flowing performance components allows exhaust gases to leave the engine more efficiently while retaining compatibility with the original Porsche exhaust tips.
Manufactured from 14–16 gauge CNC mandrel-bent T304L stainless steel, the Maxflo system combines performance-oriented exhaust flow with excellent resistance to heat, corrosion and repeated thermal cycling.
Fabspeed reports gains of approximately 8 wheel horsepower and 10 ft-lb of torque, together with a 12 lb reduction in weight compared with the factory components.
What This Product Does:
The Maxflo Performance Exhaust replaces the original rear mufflers.
The mufflers form an important part of the exhaust system, controlling exhaust noise while providing a route for gases leaving the engine.
A performance muffler system reduces unnecessary restriction while maintaining sufficient sound control for its intended application.
The Fabspeed Maxflo system is designed to:
- Improve exhaust-gas flow
- Reduce exhaust restriction
- Increase horsepower and torque potential
- Reduce rear vehicle weight
- Produce a deeper performance exhaust note
- Increase exhaust volume compared with the factory mufflers
- Maintain compatibility with OEM exhaust tips
- Provide a durable stainless-steel replacement for ageing factory mufflers
Improved Exhaust Flow:
The naturally aspirated Porsche 996 GT3 engine depends on efficient intake and exhaust flow to produce power throughout the rev range.
Excessive exhaust restriction makes it more difficult for gases to leave the engine efficiently.
The Maxflo system uses freer-flowing mufflers and mandrel-bent tubing to provide a smoother exhaust path.
Potential benefits include:
- Improved exhaust evacuation
- Reduced restriction
- Improved engine breathing
- Sharper throttle response
- Improved power delivery
- Increased performance potential throughout the RPM range
Manufacture Reported Performance:
Fabspeed reports dyno-tested gains of approximately:
Power: +8 WHP
Torque: +10 ft-lb
Weight Reduction: Approx. 12 lb
These figures are manufacturer-reported results obtained from a specific test vehicle and should not be considered guaranteed gains for every 996 GT3.
Actual results can vary according to:
- Engine condition
- Existing exhaust configuration
- Intake modifications
- Engine calibration
- Fuel quality
- Ambient temperature
- Vehicle specification
- Testing equipment and methodology
More Aggressive GT3 Exhaust Sound:
One of the principal benefits of the Maxflo system is its enhanced exhaust character.
The factory GT3 exhaust provides a relatively controlled sound for road use. The Fabspeed system allows more of the naturally aspirated flat-six character to be heard.
The result is designed to provide:
- Deeper exhaust tone
- More aggressive sound under acceleration
- Stronger flat-six character
- Increased presence throughout the RPM range
- More exotic performance-car sound
Fabspeed specifically designs the system to provide this more aggressive character while keeping cabin drone to a minimum.
Final exhaust volume and tone will depend on the other exhaust components fitted to the vehicle.
Why Upgrading Matters:
The factory exhaust does not need to have failed for the Maxflo system to be installed.
This is primarily a performance upgrade designed for owners who want increased exhaust character, improved flow and reduced weight.
Reasons for upgrading include:
- Improved exhaust flow
- Reduced restriction
- Manufacturer-reported +8 WHP
- Manufacturer-reported +10 ft-lb
- Approx. 12 lb weight reduction
- More aggressive GT3 exhaust sound
- Minimal cabin drone by performance-exhaust standards
- T304L stainless-steel construction
- CNC mandrel-bent tubing
- Compatibility with factory exhaust tips
- Bolt-on installation
- No cutting or welding required
