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 motorway trips. If you do a lot of motorway driving, compare it with the resonated version.
• What about the neighbors in the morning? The valves are controlled as on the original: closed and discreet at startup or in comfort mode, fully open in sport mode.
• Fitting: installation requires cutting the original exhaust. We recommend having it fitted by a professional.

Why choose Milltek Sport?

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