Our most frequently asked questions

• Do I need an ECU remap? Yes. A suitable Stage 2 map is essential to get the gain and avoid a check engine light linked 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.
• Line compatibility: this downpipe connects to the OEM exhaust line.

Why choose Milltek Sport?

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