iE Catback Exhaust System – Audi S3 8Y (2022+)

Give your 2022+ Audi S3 a louder, cleaner exhaust note and real performance benefits with the iE Catback Exhaust. Engineered from T304L stainless steel, this system uses iE’s DroneTrap resonator to control cabin drone while large 3-inch primary piping and 2.5-inch tailpipes support high flow. Bold quad 4-inch slash-cut tips complete the motorsport look. The kit is a direct bolt-on with the factory downpipe or the iE downpipe. No cutting and no welding required.

Leading Features

• Aggressive yet refined exhaust tone with minimal cabin drone
• DroneTrap no-drone resonator targets problem frequencies
• Quad 4-inch slash-cut tips with brushed motorsport finish
• 3-inch mandrel-bent primary piping to 2.5-inch tailpipes for high flow
• Easy, no-cut, no-weld installation
• Direct bolt-on with stock or iE downpipe
• Premium T304L stainless steel with TIG-welded joints

Sound

Enjoy a deeper, louder character under throttle with a smooth cruise on the highway. DroneTrap technology captures drone-causing sound waves and leaves the tone you want — a rich, full-bodied exhaust note at all RPMs.

Design

Quad 4-inch slash-cut tips are adjustable for depth so you can fine-tune the rear valance fit. Flow-optimized routing and a performance muffler design deliver response and tone while maintaining day-to-day driveability.

Built to Endure

• T304L stainless steel resists corrosion
• TIG-welded joints for strength and long service life
• Reinforced hangers stabilize mounting points and reduce vibration
• Stamped, multi-wall muffler body helps prevent warping
• Wide-width stretch clamps maintain tight, leak-free connections

Installation

This catback is designed for a direct bolt-on fit. Typical install time is 1–2 hours with basic hand tools. A lift is helpful but not required.
