Most frequently asked questions

• Does it require an ECU tune? Yes. A matching ECU map (Stage 2) is essential to unlock the gains 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.
• What about the French technical inspection? A decat downpipe will not pass the emissions inspection. This product is intended for motorsport use only.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, using mandrel-bent tubing to preserve the inner diameter and a fitment developed on the vehicle itself. The result: a clean installation without modifications, and a tuned sound that stays pleasant for everyday driving.
