Frequently asked questions

• Do you need an ECU remap? Yes. A suitable map (Stage 2) is essential to get the gain and avoid a check engine light linked to the lambda sensors. It is the most common question from buyers, and the answer is always the same.
• 200-cell high-flow catalytic converter: it keeps genuine emissions control while flowing far more than the original. It is the choice of tuners who want to keep their vehicle clean.
• Line compatibility: this downpipe is designed to connect to a Milltek line. Check the correct version if you keep the original line.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, with mandrel-bent tubing to preserve the internal diameter and a vehicle-specific fit. Result: a clean installation with no modification, and a sound tuned to remain pleasant for daily use.
