Most frequently asked questions

• Resonated or non-resonated? This version is non-resonated (no resonator): it is the most expressive, with more crackle on lift-off. In return, a slight drone may appear at certain engine speeds on long trips. If you do a lot of motorway driving, compare with the resonated version.
• What about the neighbors in the morning? The valves are controlled as on the original: line closed and discreet on startup or in comfort mode, fully open in sport mode.
• Installation: the line 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, using mandrel-bent tubes to preserve the internal diameter and a fit developed on the vehicle. Result: a clean fitting with no adaptation needed, and a tone tuned to remain pleasant for everyday driving.
