Our most 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. 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 neighborhood in the morning? The valves are controlled as on the original: 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 usually fits it in one to two hours.

Why choose Milltek Sport?

Milltek Sport designs and builds its exhausts in England, with mandrel-bent tubes to preserve the inner diameter and a fit developed on the vehicle. The result: a clean installation with no modification needed, and a tone tuned to stay pleasant for daily driving.
