Our most frequently asked questions

• Is ECU tuning required? Yes. A suitable ECU map (Stage 2) is essential to make use of the gain and to avoid a check engine light related to the lambda sensors. This is the question buyers ask most, and the answer is always the same.
• 200-cell sport catalytic converter: it retains genuine emissions control while flowing significantly more than the original. It is the choice of tuners who want to keep their 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 for European tuners, Milltek Sport develops each of its systems directly on the vehicle. Mandrel-bent tubing, clean welds and aerospace-grade stainless steel ensure a system that lasts and sounds right.
