DESIGN DETAILS
STRONG, REINFORCED, RELIABLE
IE's advanced DroneTrap technology captures the pulse waves responsible for your B9 3.0T engine's exhaust note and draws them into dual mathematically tuned resonators. The internal ports are engineered to resonate these waves against each other in a process that selectively cancels out those responsible for annoying drones. The remaining waves produce the deepened and enriched exhaust acoustics you love.
QUAD SLASH-CUT TIPS
What is the point of a larger exhaust that looks stock? Stand out from the crowd with oversized 90mm quad slash-cut exhaust tips. These aggressive-looking tips fill the factory exhaust cutouts for that high-end sporty look.
COMPLETE BOLT-IN KIT
Our catback design includes all sections to replace the factory exhaust tips, mufflers, and resonator up to the midpipes. Enjoy an unrestricted system that delivers the perfect exhaust note from your turbocharged V6 engine.
OPTIONAL MIDPIPES
Want to take your catback to the next level? Add a set of IE Midpipes for an even larger boost in sound. By upgrading this section, you'll remove the two factory resonators and 12 feet of exhaust piping, further improving exhaust flow and acoustic notes.
Midpipe upgrade is optional, and the catback can be installed with either stock or IE midpipes.
ADVANCED ENGINEERING
Advanced 3D scanning tools and cutting-edge software provide our engineers with a high-resolution digital model of the Audi B9 S4 chassis. This data is then used to maximize the exhaust size for flow and optimize all available space for the perfect catback fitment.
TIG WELDED T304L STAINLESS STEEL
All piping is constructed of mandrel-bent T304L stainless steel to offer superior corrosion resistance. All joints are hand TIG welded using precise fixtures and tooling. We take great pride in knowing your new exhaust will sound remarkable and stand the test of time.
STAMPED RESONATOR
The DroneTrap system is wrapped up in our stamped multi-wall resonator that reinforces the housing inside and out. This high level of manufacturing protects the resonator from warping or splitting at the welds under exhaust movement.
REINFORCED HANGERS
Engine movement and exhaust weight are transferred into the exhaust hangers, which puts a lot of stress on the mount brackets. IE's catback system is manufactured with multi-point and boxed-in hanger mounts designed to stand the test of time. Drive confidently knowing your exhaust is securely mounted and protected against annoying rattles or breaks.
BRIDGED PIPING
Sections comprised of dual 2.5" piping running in parallel are reinforced and bridged to offer superior strength and weight dispersion. This minor detail works hard to reduce stress on the welds and protect the piping from vibrations and twisting that can lead to leaks and rattles.
LEAK-FREE CLAMPS
Enjoy a tuned and enjoyable exhaust note without any raspy leaks ruining the show. Our exhaust system assembles with our wide-width stretch clamps designed to seal and pull your exhaust connections together. This style of clamp design is popular in high-end OE applications and is known for long-term reliability.
