Most frequently asked questions

• Does it require an ECU tune? Yes. A proper Stage 2 ECU map is essential to make use of the gain and avoid a check engine light related to the lambda sensors. It is the question buyers ask most often, and the answer is always the same.
• High-flow catalytic converter, 200 cell: it retains real emissions control while flowing much more than the factory unit. It is the choice of tuners who want to keep their vehicle clean.

Why choose Milltek Sport?

What owners most often mention in feedback: fit quality and a deep tone that is present but never harsh. This is the Milltek Sport trademark, from a British manufacturer specialized in stainless steel exhausts.
