ARM Catted Downpipe - Audi B9 S4/S5 3.0T
The ARM B9 S4 Catted Downpipe gives your Audi 3.0T EA839 engine all the power with less emissions! It allows for more exhaust flow from the turbocharger while keeping exhaust fumes lower. This allows your 3.0T to spool faster, increasing power, and improving throttle response, especially in the lower RPM range. On top of all of these performance benefits, the ARM B9 3.0T Downpipe upgrade opens up the sound of your 3.0T especially when paired with the ARM B9 Midpipes, giving you the sound to match!
Check out the video below to hear the sound difference the ARM Downpipe and ARM Midpipes makes versus the OEM downpipe and midpipes.
The OEM 3.0T downpipe utilizes a large 800 cell catalyst that restricts vital airflow out of the engine. The ARM B9 3.0T Downpipe replaces this restrictive section of the exhaust with a 200 cell catalyst, allowing you to free up more power from your 3.0T!

- Increased Power and Torque
