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 be noticeable at certain engine speeds on long trips. If you do a lot of motorway driving, compare it with the resonated version.
• Valveless: the system sounds at all times. On a vehicle fitted with factory valves, a valve delete kit may be required to avoid a warning light (see fitting information).
• Fitting: the system uses the original mounting points. A repair shop typically fits it in one to two hours.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhaust systems in England, with mandrel-bent tubes to preserve the internal diameter and a fit developed on the vehicle. The result: a clean fitting with no modification required, and a sound tuned to stay pleasant for daily driving.
