Frequently asked questions

• Is an ECU tune required? Yes. A Stage 2 ECU map is essential to get the full gain and avoid an engine warning light linked to the lambda sensors. It is the most common question from buyers, and the answer is always the same.
• High-flow sport cat, 200 cells: it still provides real emissions control while flowing considerably more than the original. It is the choice of tuners who want to keep the vehicle emissions-compliant.
• Exhaust compatibility: this downpipe is designed to connect to a Milltek exhaust system. Check the correct version if you keep the original exhaust.

Why choose Milltek Sport?

A benchmark 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.
