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 may appear at certain engine speeds on long journeys. 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 quiet on startup or in comfort mode, fully open in sport mode.
• Installation: 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 manufactures its exhausts in England, using mandrel-bent tubes to preserve the internal diameter and a fit developed on the vehicle. The result: a clean installation, no modification needed, and a tone tuned to stay pleasant for everyday driving.
