Active Autowerke Catted Downpipe
What is this beast?
Sheeesh! If you just dropped 80 grand on a brand new Gen3 B58 car, you probably don't want it smelling like a 1990s Honda Civic. Active Autowerke is the solution. This is an ultra-premium downpipe that uses an EPA-approved GESI catalytic converter. It flows almost as well as a straight pipe, giving you rapid turbo spool and that aggressive Stage 2 horsepower, but it scrubs the exhaust gases perfectly. No nasty smells, no failing emissions, and absolutely zero Check Engine Lights. Pure class and pure speed.
Why the stock part is absolute pain
The biggest headache of a catless downpipe is the smell and the dashboard warning lights. The AA Catted Downpipe eliminates both pains natively. You don't need any software hacks or O2 spacers to keep the ECU happy. The GESI core is built to withstand extreme heat and pressure, so it won't melt when you're doing highway pulls. It gives your Gen3 a deep, rich, throaty exhaust note without being obnoxious. It’s the perfect upgrade for a luxury daily driver.
