Make your presence known with the feral sound of the iE Catback for the Audi B9 S5 Sportback and Coupe. Thanks to our proprietary DroneTrap technology, you get unrestrained ferocity without drone. Engineered with mandrel-bent stainless steel, TIG welding, multi-point reinforcements, and oversized quad tips, it’s beauty and beast all in one.
iE’s advanced DroneTrap technology uses mathematically-tuned resonators to cancel out the soundwaves that cause drone, leaving the audacious, feral waves free to conjure deep, satisfying roars and rumbles.
Add a dash of non-stock flair with oversized, 90mm quad slash-cut exhaust tips. These aggressive-looking tips fill the factory exhaust cutouts for that high-end, sporty look.
Sound may be the primary feature of the Catback Exhaust, but durability and reliability play a significant role. This catback is made from mandrel-bent T304L stainless steel, featuring hand-TIG-welded joints and several structural details for added strength and integrity. The stamped, multi-wall muffler prevents warping, while reinforced hangers ensure a secure mounting. Strength-boosting bridged piping distributes weight, reducing stress and vibration. Wide-width stretch clamps ensure tight and leak-free connections.
