Frequently asked questions

• Resonated or non-resonated? This version is non-resonated (no resonator): the most expressive, with more crackle on lift-off. The trade-off is a slight drone that can appear at certain engine speeds on long trips. If you do a lot of highway driving, compare it with the resonated version.
• Valveless: the system sounds off at all times. On a vehicle with factory exhaust 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 properly equipped repair shop typically fits it in one to two hours.

Why choose Milltek Sport?

A benchmark among European tuners, Milltek Sport develops each of its systems directly on the vehicle. Mandrel bending, careful welds and aerospace-grade stainless steel make for a system that lasts and sounds right.
