Most frequently asked questions

• Is an ECU remap required? Yes. A suitable Stage 2 map is essential to get the full gain and avoid a check engine light linked to the lambda sensors. It is the question buyers ask most often, and the answer is always the same.
• Emissions inspection? A decat downpipe does not pass the emissions test. This product is reserved for motorsport use.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, with mandrel-bent tubes to preserve the internal diameter and a fit developed on the vehicle. Result: a clean installation with no modification needed, and a sound tuned to remain pleasant for daily driving.
