Our most frequently asked questions

• Is an ECU remap required? Yes. An adapted map (Stage 2) is essential to get 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.
• And the French roadworthiness inspection (contrôle technique)? A decat downpipe does not pass the emissions inspection. This product is intended for motorsport use only.
• System compatibility: this downpipe is designed to connect to a Milltek system. Check the version suited to your application if you keep the original exhaust system.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, using mandrel-bent tubing to preserve the internal diameter and a fit developed on the vehicle. The result: a clean fitting with no modification, and a sound tuned to remain pleasant for everyday driving.
