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.

Constructed from T304L high-quality stainless steel, Fabspeed Motorsport AMG GT/GTR/GTS Sport Catalytic Converters offer premier quality catalysts by utilizing HJS Germany Tri-Metallica 200 cell catalysts. We perfectly match the sound expected of the AMG GT cars by dramatically improving sound and power throughout the RPM range offering a much-needed solution to the boring factory exhaust. 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 sound and reduce backpressure allowing for much quicker turbocharger spooling and transient turbo response. Fabspeed sport cats replace the restrictive OEM 800 cell catalytic converters with HJS Emissions Technology catalysts guaranteeing NO CEL (Check Engine Light) (on US cars only).


Aside from the factory catalytic converters, the Audi RS6/RS7 has an extremely free flowing exhaust. So the best way to get more sound out of it is to replace the restrictive factory catalytic converters. These Sport Cats will make your Audi RS6/RS7 sound much more aggressive. It really brings out the V8 sound from the 4.0L powerplant. Pops, bangs and crackles will be much louder and sharper. Best of all, there is no interior drone whatsoever.


We dyno tested these Sport Cats on our in-house Dynojet. At the wheels, we saw max gains of +21 whp (or +25 hp at the crank) and +42 ft/lbs TQ.

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.
