Our most frequently asked questions

• Is a remap required? Yes. A suitable ECU map (Stage 2) is essential to get the gain and to avoid an engine warning light linked to the lambda sensors. It is the question buyers ask most, and the answer is always the same.
• What about the contrôle technique? A decat downpipe does not pass the emissions test. This product is intended for motorsport use only.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, with mandrel-bent tubes to preserve the inner diameter and fitment developed on the vehicle. The result: a clean fit without modification, and a sound tuned to remain pleasant for everyday use.
