Most frequently asked questions

• Is a remap required? Yes. A proper Stage 2 ECU map is essential to realize the gain and avoid a check engine light caused by 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 maintains real emissions control while flowing much more than the OE unit. It is the choice of tuners who want to keep a vehicle clean.
• Exhaust line compatibility: this downpipe connects to the OE exhaust line.

Why choose Milltek Sport?

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