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 highway driving, compare it with the resonated version.
• No valves: the exhaust sounds off at all times. On a vehicle fitted with factory valves, a valve delete kit may be needed to avoid a warning light (see fitting information).
• Fitting: the system uses the factory 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 tubing to preserve the internal diameter and a fitment developed on the vehicle. The result: a clean installation with no modifications, and a sound tuned to stay pleasant for daily driving.
