Integrated Engineering Catback Exhaust System - Audi B9 A4

Given the nature of the Audi A4 4-cylinder 2.0T, iE engineers had to do a little bit more “voice coaching” to bring out all the roars and rumbles in all the right places. It wasn’t an easy ask, but the end result is a thing of beauty. We replaced that underwhelming stock sound with a more muscular tone and none of the rasp found on downpipe-only setups. Meticulously manufactured with reinforced piping, boxed hangers, high-flow pipe design, and finely tuned mufflers for long life. Enjoy every drive with the one and only DroneTrap technology that smashes irritating drone sound waves for endless and unrestrained fun.
