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. On the downside, a slight drone can appear at certain engine speeds on long trips. If you do a lot of highway driving, compare 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 workshop equipped for the job 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 tubes to preserve the internal diameter and a fit developed on the vehicle. The result: a clean fitting without adaptation, and a sound tuned to remain pleasant for everyday use.
