Most frequently asked questions

• Is an ECU remap required? Yes. A suitable ECU map (Stage 2) is essential to get the full benefit and avoid a check engine light related to the lambda sensors. This is the question buyers ask most often, and the answer is always the same.
• What about the 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 exhaust systems in England, using mandrel-bent tubing to preserve the inner diameter and fitment developed on the vehicle itself. The result: a clean installation with no modifications needed, and a sound tuned to stay pleasant for everyday driving.
