PURCHASE DISCLAIMER: Fabspeed Motorsport does not condone the use of emission defeat devices for any vehicles used on public streets or roadways. Fabspeed Motorsport will not tamper, remove, disable, or bypass emissions equipment on a motor vehicle in accordance with 40 CFR Section 86.1854.12(a)(3), Clean Air Act 40 CFR 1068.101(b). This includes software, known as tunes, that reprogram a motor vehicles electronic control module to alter engine performance and enable the removal of filters, catalysts, and other critical emissions controls.

Get the absolute most power and sound from your 992 Twin Turbo without any check engine lights. This system exhaust mimics the valves open configuration of a 991 GT2 exhaust and because of the modular design if you find the setup too loud for everyday driving you can use the optional muffler adapter pipes so that you can reinstall the factory muffler or our Valvetronic Maxflo Exhaust.

With over 25+ years of Porsche air and water-cooled experience, Fabspeed Motorsport USA offers a great enhancement for your stock exhaust or aftermarket exhaust on your Porsche 992 Twin Turbo / Turbo S. Fabspeed was the first company to design and engineer every Porsche twin turbo exhaust enhancement. From the 1996 993TT to the 2021 twin turbo, making a sports car like the 992 Turbo / Turbo S even faster and more exclusive is the domain of Fabspeed.  Using only certified high-performance HJS components imported directly from Germany, our system eliminates all risk for black market, grey market, or counterfeit HJS catalytic converters from other companies. Increase the exotic twin turbocharged Porsche sports car sound and reduce back pressure allowing for a much quicker turbocharger spooling and transient turbo response for the 992 VTG (Variable Turbine Geometry). Fabspeed sport cats replace the restrictive OEM 800 cell catalytic converters with HJS Emissions Technology catalysts guaranteeing NO CEL (Check Engine Light).


This system provides an aggressive sound that matches the incredible power and speed of the 992 Turbo. Expect a significant increase in volume over stock more turbo spooling sounds, while burbles and pops on deceleration are much louder and sharper.


This is the most free-flowing exhaust design possible while still maintaining catalytic converters. When testing on our AWD Dynojet power was up across the board. Down low, the Turbo spools faster and harder, netting 23.7 WHP and 41.5 ft/lbs of TQ at 3000 RPM. Max power gains are at 5300 RPM where it gained 47.7 WHP and 47.1 ft/lbs of TQ. That's a gain of 54 HP at the crank! See our dyno graph above for more details.

Why we choose HJS catalytic converters:

HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.    If you'd like to learn more, watch our video about HJS catalytic converters.

You are hereby informed and warned to check your local, state, and federal laws before buying and installing these or any aftermarket parts to be sure whether usage is in violation.
