Your stereo is obsolete. Make your presence known with the feral sound of the iE Catback Exhaust System for the Audi B9 S5 Sportback. Engineered with iE’s proprietary DroneTrap technology, this exhaust delivers an aggressive tone without the drone—unleashing a deep, refined roar that turns every drive into an experience.
iE DroneTrap Technology: Designed through advanced acoustic engineering, the DroneTrap resonator uses precisely tuned chambers to capture and cancel drone frequencies while amplifying the deep, throaty tones enthusiasts crave. The result is a powerful, high-performance exhaust that stays civil at cruise yet roars to life under throttle.
Quad Slash-Cut Tips: Oversized 90mm stainless steel tips fill the factory cutouts perfectly, offering a premium, aggressive look that matches the system’s sound. Each tip features a precision slash-cut finish that enhances the S5’s rear aesthetics.
Built to Endure: Crafted from mandrel-bent T304L stainless steel with hand TIG-welded joints, this system is built for strength and reliability. Reinforced hangers, bridged piping, and multi-wall mufflers ensure structural integrity and a long service life. Stretch-fit clamps provide tight, leak-free connections without hassle.
Installation: Simple, bolt-on installation with basic tools—no cutting or welding required. An auto lift is recommended for convenience.
Average install time: 3–4 hours.
