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 may appear at certain engine speeds on long highway trips. If you do a lot of motorway driving, compare it with the resonated version.
• And the neighbors in the morning? The valves are controlled as on the factory system: closed and discreet on startup or in comfort mode, fully open in sport mode.
• Fitting: the system uses the original mounting points. A workshop typically fits it in one to two hours.

Why choose Milltek Sport?

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