Frequently asked questions

• Is an ECU tune required? Yes. A suitable Stage 2 map is essential to realize the gain and avoid an engine warning light linked to the lambda sensors. This is the most frequently asked question from buyers, and the answer is always the same.
• 200-cell sport catalyst: it maintains real emissions control while allowing much more flow than the original. It is the choice of tuners who want to keep a vehicle clean.
• Line compatibility: this downpipe is designed to connect to a Milltek line. Check the suitable version if you keep the original line.

Why choose Milltek Sport?

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