Frequently asked questions

• Resonated or non-resonated? This version is non-resonated (no resonator): it is the most expressive, with more crackle on throttle lift-off. On the other hand, a slight drone may 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 operate as on the factory system: closed and quiet on startup or in comfort mode, fully open in sport mode.
• Installation: fitting requires cutting the factory exhaust. We recommend having it installed by a professional.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, using mandrel-bent tubes to preserve the inner diameter and a fit developed on the vehicle. The result: a clean installation with no modification required, and a sound tuned to stay pleasant every day.
