Frequently asked questions

• Is a remap required? Yes. A suitable Stage 2 tune is essential to make the most of the gain and avoid a check engine light caused by the lambda sensors. This is the question buyers ask most often, and the answer is always the same.
• What about the contrôle technique? A decat downpipe will 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, using mandrel-bent tubing to preserve the internal diameter and a fitment developed on the vehicle. The result: a clean fit with no adaptation required, and a sound tuned to remain pleasant for daily driving.
