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. The trade-off is that a slight drone can appear at certain engine speeds on long drives. 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 original system: closed and quiet at startup or in comfort mode, fully open in sport mode.
• Installation: the system uses the original mounting points. A well-equipped repair shop typically fits it in one to two hours.

Why choose Milltek Sport?

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