Most frequently asked questions
- Is a remap required? Yes. A suitable ECU map (Stage 2) is essential to get the full benefit of the gain and to 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 genuine emissions control while flowing considerably more than the original. It is the choice of tuners who want to keep their vehicle clean.
Why choose Milltek Sport?
Milltek Sport designs and manufactures its exhausts in England, using mandrel-bent tubing to preserve the internal diameter and a fitment developed on the vehicle. The result: a clean installation with no modifications, and a sound tuned to stay pleasant for daily driving.
