OVERSIZED SLASH-CUT TIPS

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.

iE DRONETRAP TECHNOLOGY

DroneTrap is iE's 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.

It’s not just the sound that the iE Catback delivers. They always bring their A-game to serve up exceptional designs made from built-to-last materials for installs that fit like a glove. iE's 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.

WANT IT LOUDER?

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.
