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.

iE DroneTrap is our defense against the sound waves that kill your exhaust note listening experience. This proprietary technology captures and mutes soundwaves that cause annoying drones, leaving only the good stuff you’re into—a full, deep, rich, and audacious call of the wild.

Lift your A4's style to new heights and look good doing it with these large 90mm exhaust tips. The slash-cut tips feature a motorsport-inspired brushed finish with adjustable depth, great for dialing your aggressive looks up or down.

Delivering head-turning exhaust sound is just one part iE's catback game. There’s plenty left to say in the design and engineering department too. This exhaust is made from corrosion-resistant, mandrel-bent T304L stainless steel with strong, multi-point, boxed exhaust hangers for long life and reinforced with bridged sections to prevent rattles. Always sound your best with the leak-free, OE-quality exhaust clamps.
