Frequently asked questions

• Resonated or non-resonated? This version is non-resonated (no resonator): it is the most expressive, with more crackle on lift-off. On the other hand, a slight drone can appear at certain engine speeds on long trips. If you do a lot of highway driving, compare it with the resonated version.
• No valves: the system sounds at all times. On a vehicle with factory valves, a valve delete kit may be needed to avoid a warning light (see fitting information).
• Fitting: the system uses the original mounting points. A workshop typically fits it in one to two hours.

Why choose Milltek Sport?

What comes up most often in owner feedback: fit quality and a deep sound that is present but never harsh. That is the Milltek Sport signature, from a British manufacturer specializing in stainless steel exhausts.
