Frequently asked questions

• Resonated or non-resonated? This version is non-resonated: it is the most expressive, with more crackle on lift-off. On the downside, 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.
• Fitting: the system uses the original mounting points. A shop with the right equipment typically fits it in one to two hours.

Why choose Milltek Sport?

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