Frequently asked questions

• Is ECU tuning required? Yes. A matching ECU map (Stage 2) is essential to get the full gain and avoid a check engine light linked to the lambda sensors. This is the question customers ask most often, and the answer is always the same.
• 200-cell high-flow catalytic converter: it keeps real emissions control while flowing far more than the original. 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 system. Check which version fits if you keep the original exhaust.

Why choose Milltek Sport?

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