Most frequently asked questions

• Does it require an ECU tune? Yes. A proper Stage 2 ECU map is essential to make use of the gain and avoid a check engine light related to the lambda sensors. It is the question buyers ask most often, and the answer is always the same.
• What about the technical inspection? A decat downpipe will not pass the emissions test. This product is intended for motorsport use only.

Why choose Milltek Sport?

A reference among European tuners, Milltek Sport develops each of its systems directly on the vehicle. Mandrel bending, careful welding and aerospace-grade stainless steel deliver an exhaust that lasts and sounds right.
