Most frequently asked questions

• Is an ECU tune required? Yes. A matching Stage 2 ECU map is essential to get the full gain and avoid a check engine light caused by the lambda sensors. It is the question buyers ask most often, and the answer is always the same.
• High-flow sport catalytic converter, 200 cells: it keeps real emissions control while flowing considerably more than the stock unit. It is the choice of tuners who want to keep their car clean.

Why choose Milltek Sport?

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