Cat-back valvetronic Maxflo exhaust system. Porsche 992 Twin Turbo / Twin Turbo S ❭ FSPOR992TVLV
- Porsche 992.1 Turbo 3.8L 2020-24
- Porsche 992.1 Turbo S 3.8L 2020-24
- Porsche 992.1 Turbo Cabriolet 3.8L 2020-24
- Porsche 992.1 Turbo S Cabriolet 3.8L 2020-24

Treat your 992 Turbo to the finest cat-back exhaust solution on the market. This valveed exhaust system is plug-and-play with the factory PSE system so you can turn PSE off for quiet highway cruising and turn PSE on for ripping Twin Turbo sports car sound!
SOUND:
With PSE on and valves open, the Cat-Back Valvetronic Maxflo Exhaust turns your 992's exhaust note into a true neck-breaker with a significant increase in volume. Get a deep tone and aggressive pops on downshift as well as turbo spooling sounds. With PSE off and the valves closed the exhaust note is tame and totally drone-free. In-cabin conversations are just as easy as they were with the stock exhaust.
POWER:
With our signature cast X-pipe and all cnc mandrel-bent tubing, this system significantly outflows the factory system. When testing on our AWD Dynojet power was up across the board. Down low, the Turbo spools faster, netting 19.6 WHP and 32.7 ft/lbs of TQ at 3100 RPM. Max power gains are at 4800 RPM where it gained 48.7 WHP and 53.7 ft/lbs of TQ. That's a gain of 55 HP at the crank! See our dyno graph above for more details.
FEATURES:
• Fits all Porsche 992 Twin Turbo / Twin Turbo S vehicles, coupe and cabriolet worldwide (2021+)
• Dyno-proven power gains of 48.7 WHP and 53.7 ft/lbs of TQ
• Saves 9.8 lbs / 4.4 KGs compared to stock
• Completely retains PSE valved exhaust functionality
• Uses aerospace quality Helical Limited exhaust valves imported from the U.K.
• This cat-back system is emissions legal in all 50 states and the rest of the world (ROW)
• This exhaust system will have no effect on the factory warranty
• Constructed from CNC mandrel-bent 14-16 guage T304L stainless steel
• Laser scanned and CAD designed for perfect OEM fitment using an Ametek Handyscan 700
• Simple DIY (Do-It-Yourself) bolt-on installation, no cutting or welding required
• Compatible with OEM Porsche catalytic converters and Fabspeed Sport Catalytic Converters
Increased exotic Twin Turbocharged Porsche sports car sound

- Porsche 997 MKII Turbo 2010-13
The Fabspeed Supersport X-Pipe Exhaust System is a high-performance turbo-back exhaust upgrade developed for the Porsche 997.2 Turbo and Turbo S from 2010–2012.
Fits:
- Porsche 997 MKII Turbo / Turbo S 2010-12
Designed to replace the heavy and restrictive factory rear mufflers and catalytic-converter section, the system improves exhaust-gas flow while producing a significantly stronger and more engaging Porsche flat-six exhaust note.
What This Product Does:
The exhaust system carries hot combustion gases away from the turbochargers and through the rear of the vehicle.
On a turbocharged engine, reducing unnecessary restriction after the turbochargers can improve exhaust flow and help the complete engine and turbo system operate more efficiently.
The Fabspeed Supersport X-Pipe replaces restrictive factory exhaust components with a freer-flowing performance design.
Its purpose is to provide:
- Improved exhaust-gas flow
- Reduced exhaust restriction
- Improved power potential
- Stronger performance throughout the RPM range
- More noticeable turbo spool sound
- A deeper and sportier flat-six exhaust note
- Reduced exhaust-system weight
- More aggressive rear styling
- Improved driving character
When Might This Exhaust Upgrade Be Worth Considering:
The Fabspeed Supersport X-Pipe is primarily a performance upgrade, rather than a component that requires routine replacement.
It may be considered when:
- More exhaust sound is desired
- Improved turbo sound is wanted
- The factory exhaust feels too restrictive
- A freer-flowing performance exhaust is required
- Increased performance potential is desired
- Reduced exhaust-system weight is beneficial
- A more aggressive rear appearance is wanted
- The original mufflers or catalytic converters are damaged
- The vehicle is being prepared for further performance upgrades
Why Replacement Matters:
A damaged or leaking exhaust system should not be ignored.
Exhaust leaks can allow extremely hot gases to escape before reaching the intended outlet.
Depending on the location and severity of the fault, this may cause:
- Excessive exhaust noise
- Exhaust fumesSoot deposits
- Heat damage to surrounding components
- Reduced exhaust-system efficiency
- Incorrect oxygen-sensor readings
- Engine-management faults
- Poor exhaust sealing
Replacing deteriorated components restores the integrity of the exhaust system.
For owners choosing the Fabspeed Supersport system as an upgrade, replacement also provides an opportunity to improve exhaust flow, reduce weight and significantly enhance the sound of the 997.2 Turbo or Turbo S.
