Frequently Asked Questions

• Highway drone? It is the number one concern on forums. This version keeps a resonator: the tone stays full under acceleration, while the exhaust remains calm at steady cruising speed, ideal for everyday driving.
• Fitment: the system uses the original mounting points. A shop equipped for the job 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 a fitment developed on the vehicle. The result: a clean installation with no modification required, and a tone tuned to stay pleasant for daily use.
