Frequently asked questions

• Do I need ECU tuning? Yes. A suitable Stage 2 map is essential to get the full gain and avoid a check engine light caused by 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 the vehicle emissions-compliant.
• Line compatibility: this downpipe connects to the factory exhaust line.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, with mandrel-bent tubes to preserve the internal diameter and a fitment developed on the vehicle. The result: a clean installation without modification, and a tone tuned to stay pleasant for daily driving.
