Most frequently asked questions

• Is an ECU remap required? Yes. A suitable Stage 2 map is essential to get the full 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 cat: it keeps real emissions control while letting through much more flow than stock. It is the choice of tuners who want to keep a vehicle clean.
• Exhaust compatibility: this downpipe is designed to connect to a Milltek exhaust line. Check the correct version if you keep the original exhaust line.

Why choose Milltek Sport?

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