Most common questions

• Is a remap required? Yes. A suitable ECU map (Stage 2) is essential to get the gain and to avoid an engine warning light linked to the lambda sensors. It is the most frequently asked question from buyers, and the answer is always the same.
• 200-cell sport catalytic converter: it retains real emissions control while letting through far more flow than stock. It is the choice of tuners who want to keep their vehicle clean.
• Line compatibility: this downpipe connects to the stock exhaust line.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, using mandrel-bent tubes to preserve the inside diameter and a fit developed on the vehicle. The result: a clean installation with no adjustment needed, and a sound tuned to stay pleasant for everyday driving.
