Milltek Sport Exhaust System for Audi S3 8V2

Frequently asked questions

• Highway drone? It's the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, but the system remains calm at steady cruising speed, ideal for daily driving.
• Valveless: the system stays loud at all times. On a vehicle fitted with factory valves, a valve delete module may be needed to avoid a warning light (see fitment details).
• Installation: the system uses the original mounting points. A well-equipped repair shop typically fits it in one to two hours.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, using mandrel-bent tubing to preserve the internal diameter and fitment developed on the vehicle. The result: a clean installation with no modification required, and a sound tuned to stay pleasant for everyday use.
