Frequently asked questions

• Is an ECU remap required? Yes. A suitable ECU map (Stage 2) 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.
• 200-cell sport catalytic converter: it maintains real emissions control while flowing far more than the factory unit. It is the choice of tuners who want to keep a clean vehicle.

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. The result: a clean installation, no modification needed, and a sound tuned to stay pleasant for everyday driving.
