Our most frequently asked questions

• Resonated or non-resonated? This version is non-resonated (no mid resonator): it is the most expressive, with more crackle 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 highway driving, compare it with the resonated version.
• Without valves: the system sounds the same at all times. On a vehicle 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. A workshop equipped for the job typically fits it in one to two hours.

Why choose Milltek Sport?

What users mention most often: fit quality and a deep sound that is present but never harsh. This is the signature of Milltek Sport, a British manufacturer specializing in stainless steel exhausts.
