Our most frequently asked questions

• Resonated or non-resonated? This version is non-resonated (no resonator): it is the most expressive, with more crackling on lift-off. On the other hand, a slight drone may appear at certain engine speeds on long journeys. If you do a lot of motorway driving, compare it with the resonated version.
• What about the neighbors in the morning? The exhaust 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 factory mounting points. A repair shop with the right equipment typically fits it in one to two hours.

Why choose Milltek Sport?

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