Most frequently asked questions

• Is a remap required? Yes. A suitable ECU map (Stage 2) is essential to get the full gain and avoid a check engine light caused by the lambda sensors. It's the question buyers ask most, and the answer is always the same.
• What about the roadworthiness inspection? A decatted downpipe will not pass the emissions inspection. This product is reserved for motorsport use.
• Line compatibility: this decat pipe is designed to connect to a Milltek exhaust system. Check the version suited to your application if you keep the original exhaust.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhaust systems in England, using mandrel-bent tubing to preserve the internal diameter and a fitment developed on the vehicle. The result: a clean installation without modification, and a sound tuned to stay pleasant every day.
