Treat your 992 Twin Turbo, Turbo S, or Turbo “50 Years” edition to the finest cat-back exhaust solution available. The Fabspeed Valvetronic Exhaust is fully plug-and-play with Porsche PSE, allowing quiet highway cruising with PSE off or an aggressive, open-valve experience when PSE is on.

With over 30 years of air-cooled and water-cooled Porsche experience, Fabspeed Motorsport USA continues to elevate the 992 platform. Fabspeed was the first to design and engineer valved exhaust systems for every Porsche Twin Turbo model—from the 1996 993TT to today’s 992 Turbo and Turbo S. This system uses certified Helical Aerospace valves imported from the U.K., the same manufacturer trusted by OEMs like Porsche, Ferrari, Lamborghini, McLaren, and Aston Martin.

SOUND

Click to experience the Fabspeed sound →

With PSE on and valves open, this system delivers a deep, aggressive exhaust note with crisp pops, sharper turbo spooling, and an unmistakable presence. With PSE off and valves closed, the tone becomes quiet and refined, completely drone-free.

POWER

With the signature Fabspeed cast X-pipe and CNC mandrel-bent stainless tubing, airflow dramatically surpasses the factory system. On the AWD Dynojet, the 992 Turbo gained:

  • +19.6 WHP and +32.7 ft/lbs TQ at 3100 RPM
  • +48.7 WHP and +53.7 ft/lbs TQ at 4800 RPM
  • ≈ +55 HP at the crank

FEATURES

  • Fits all Porsche 992 Twin Turbo / Turbo S / Turbo “50 Years” (2021+)
  • Dyno-proven gains of +48.7 WHP / +53.7 ft/lbs TQ
  • Saves 9.8 lbs (4.4 kg) vs. stock
  • Retains full Porsche PSE valved functionality
  • Equipped with aerospace-grade Helical Limited valves imported from the U.K.
  • 50-state emissions legal (and ROW-legal)
  • No effect on factory Porsche warranty
  • Constructed from CNC mandrel-bent T304L stainless steel
  • Laser-scanned and CAD-designed for perfect OEM fitment
  • DIY bolt-on installation — no cutting or welding
  • Compatible with OEM catalytic converters and Fabspeed Sport Cats
  • Produces an exotic turbocharged Porsche exhaust note
  • Backed by the Fabspeed Lifetime Warranty

The Difference Between Cat-Back & Axle-Back Exhausts

A cat-back system replaces the muffler, tips, and all piping leading to the catalytic converter. An axle-back system replaces only the tips and muffler. Both enhance sound and performance, but a cat-back offers greater flow improvements and bigger gains.

The Fabspeed Cat-Back Valvetronic Maxflo Exhaust provides emissions-legal power gains, refined appearance, and full valve control using Helical Limited aerospace-grade valves.

If you’re shopping across Porsche models, note that the Porsche Macan rear slip-on exhaust (2018–2022) is not compatible with the 992 platform. Select the system designed specifically for the 992 Turbo or Turbo S.
