Most frequently asked questions

• Resonated or non-resonated? This version is non-resonated (without 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 trips. If you do a lot of motorway driving, compare it with the resonated version.
• No valves: the system sounds at all times. On a vehicle fitted with factory valves, a valve delete module may be needed to avoid a warning light (see fitting information).
• Fitting: the system uses the original mounting points. An 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 inner diameter and a fit developed on the vehicle. Result: a clean installation with no modification, and a sound tuned to stay pleasant for everyday use.
