Our most 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. The trade-off is that a slight drone may appear at certain engine speeds on long highway trips. If you do a lot of highway driving, compare it with the resonated version.
• No valves: the exhaust 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).
• Race version: the loudest in the range, designed for the track and for sound enthusiasts. It is not intended for quiet long-distance driving.
• Fitting: the system uses the original mounting points. A workshop typically fits it in one to two hours.

Why choose Milltek Sport?
