Our most frequently asked questions

• Drone on the highway? It's the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, but the exhaust stays unobtrusive at steady speed, ideal for daily driving.
• Valveless: the exhaust sounds on all the time. On a vehicle with factory valves, a valve delete module may be needed to avoid a warning light (see installation information).
• Installation: the system uses the original mounting points. A workshop typically fits it in one to two hours.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, with mandrel-bent tubes to preserve the inner diameter and a fit developed on the vehicle. Result: a clean fit with no modification needed, and a sound tuned to stay pleasant every day.
