Frequently asked questions

• Do I need a remap? Yes. A suitable Stage 2 ECU map is essential to realize the gain and avoid a warning light linked to the lambda sensors. It is the question buyers ask most, and the answer is always the same.
• What about the technical inspection? A decat downpipe does not pass the emissions inspection. This product is intended for motorsport use only.
• Line compatibility: this downpipe is designed to connect to a Milltek line. Check the correct version if you keep the original line.

Why choose Milltek Sport?

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