Our Most Frequently Asked Questions

• Highway drone? It's the number one concern on forums. This version keeps a resonator: sound stays full under acceleration, while the system stays calm at steady cruising speed, ideal for daily driving.
• Valveless: the system sounds open at all times. On a vehicle with factory valves, a valve delete kit may be needed to avoid a warning light (see installation notes).
• Installation: the system uses the factory mounting points. A 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 inner diameter and a fit developed on the vehicle. The result: a clean installation without modification, and a tone tuned to stay pleasant every day.
