Frequently asked questions

• Resonated or non-resonated? This version is non-resonated (without 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.
• Valveless: the exhaust sounds at all times. On a vehicle fitted with factory exhaust valves, a valve delete module may be required to avoid a warning light (see fitting information).
• Fitting: the line uses the original mounting points. A repair shop with the right equipment typically fits it in one to two hours.

Why choose Milltek Sport?

A reference among European tuners, Milltek Sport tunes each of its lines directly on the vehicle. Mandrel bending, neat welds and aerospace-grade stainless steel make for a line that lasts and sounds right.
