Frequently asked questions

• Resonated or non-resonated? This version is non-resonated (no resonator): the most expressive, with more crackle on lift-off. The trade-off is a slight drone that can appear at certain engine speeds on long trips. If you do a lot of highway driving, compare it with the resonated version.
• What about the neighbors in the morning? The valves are controlled as on the factory system: closed and discreet at startup or in comfort mode, fully open in sport mode.
• Fitting: the system uses the original mounting points. A properly equipped repair shop typically fits it in one to two hours.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhaust systems in England, with mandrel-bent tubing to preserve the inner diameter and a fit developed on the vehicle. The result: a clean installation with no modifications required, and a sound tuned to stay pleasant for everyday driving.
