Our most frequently asked questions

• Is an ECU remap required? Yes. A suitable Stage 2 ECU map is essential to get the gain and avoid a warning light linked to the lambda sensors. It is the most frequently asked question from buyers, and the answer is always the same.
• High-flow catalytic converter (200 cells): it retains genuine emissions control while flowing considerably more than the factory unit. It is the choice of tuners who want to keep the vehicle clean.
• Line compatibility: this downpipe is designed to connect to a Milltek line. Check the correct version if you keep the factory exhaust line.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, using mandrel-bent tubes to preserve the inner diameter and a fit developed on the vehicle. The result: a clean installation without modification, and a sound tuned to remain pleasant for everyday driving.
