Most frequently asked questions

• Resonated or non-resonated? This version is non-resonated (no resonator): the most expressive, with more crackle on lift-off. The trade-off: a slight drone can appear at certain engine speeds on long highway runs. If you do a lot of highway driving, compare with the resonated version.
• Neighbors in the morning? Valves are controlled as on the original: closed and quiet at start-up or in comfort mode, fully open in sport mode.
• Fitting: installation requires cutting the original exhaust. We recommend having a professional fit it.

Why choose Milltek Sport?

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