Our most frequently asked questions

• Is an ECU tune required? Yes. A suitable ECU map (Stage 2) is essential to get the gain and avoid an engine warning light linked to the lambda sensors. It is the question buyers ask most often, and the answer is always the same.
• 200-cell high-flow catalytic converter: it keeps real emissions control while flowing considerably more than the original. It is the choice of tuners who want to keep a vehicle clean.

Why choose Milltek Sport?

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