Frequently asked questions

• Is ECU tuning required? Yes. A matching ECU map (Stage 2) is essential to get the gain and avoid a check engine light linked to the lambda sensors. This is the question buyers ask most often, and the answer is always the same.
• 200-cell high-flow catalytic converter: it retains real emissions control while flowing considerably more than stock. This is the choice of tuners who want to keep their vehicles emissions-compliant.
• Exhaust line compatibility: this downpipe is designed to connect to a Milltek line. Check the correct version if you keep the stock exhaust line.

Why choose Milltek Sport?

A benchmark among European tuners, Milltek Sport develops each of its systems directly on the vehicle. Mandrel bends, neat welds and aerospace-grade stainless steel ensure a system that lasts and sounds right.
