Coaxing a more raw, yet refined sound from any V6 can be tough, so the Audi B8 S4 3.0T took some extra “voice coaching” from our engineers. The iE Catback Exhaust delivers a primal scream while kicking the exhaust drone to the curb via our proprietary DroneTrap technology. For bonus-style points and engineering might, the B8 S4 catback includes 90mm quad exhaust tips, dual 2.5" tubing for high-flow design and an integrated X-pipe for greater exhaust flow and superior sound.
The quad oversized 90mm exhaust tips will make your B8 S4 look fast, even when it’s standing still. These slash-cut tips feature a motorsport-inspired brushed finish with adjustable depth for dialing your aggressive looks up or down.
DroneTrap is our proprietary technology that takes away the buzz-killing drone, leaving only the sweet song of your people. It captures the pulse waves that make up the engine's exhaust note, draws them into an internal port, resonates them against each other, and cancels annoying drone waves. Only the good stuff remains—a full, rich, audacious call of the wild.
For those craving more, pairing this catback with iE Midpipes delivers a louder (yet still refined) experience. If you want to keep it on the mild side, retaining the factory midpipes will still release that addicting rumble while maintaining street-friendly levels for everyday driving.
Our catback is a bolt-on fit to both stock or iE Midpipes.
It’s not just the sound that the iE Catback delivers. We always bring our A-game to serve up exceptional designs made from built-to-last materials for installs that fit like a glove. Our Catback Exhaust is made from corrosion-resistant, mandrel-bent T304L stainless steel with strong, multi-point, boxed exhaust hangers for long life and reinforced and bridged straight sections to prevent rattles. Install kit includes all hardware and leak-free, OE-quality exhaust clamps.
