Most frequently asked questions

• Is a remap required? Yes. A suitable Stage 2 map is essential to get the most out of 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.
• 200-cell high-flow catalytic converter: it retains real emissions control while flowing considerably more than the factory unit. It is the choice of tuners who want to keep their vehicle clean.
• Exhaust compatibility: this downpipe is designed to connect to a Milltek exhaust. Check the version suited to your setup if you keep the factory exhaust.

Why choose Milltek Sport?

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