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 a slight drone that can appear at certain engine speeds on long highway trips. If you do a lot of highway driving, compare it with the resonated version.
• Installation: 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 benchmark among European tuners, Milltek Sport develops each system directly on the vehicle. Mandrel-bent tubing, careful welds and aerospace-grade stainless steel make for a system that lasts and sounds right.
