Most 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. It is the question buyers ask most often, and the answer is always the same.
- 200-cell sport 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.
Why choose Milltek Sport?
A reference among European tuners, Milltek Sport develops each of its systems directly on the vehicle. Mandrel bends, careful welds and aerospace-grade stainless steel make for a line that lasts and sounds right.
