Frequently asked questions

  • Is an ECU remap required? Yes. A suitable Stage 2 map is essential to get the full gain and avoid a check engine light related to the lambda sensors. This is the most common question from buyers, and the answer is always the same.
  • 200-cell high-flow catalytic converter: it retains real emissions control while allowing far more flow than stock. This is the choice of tuners who want to keep the vehicle emissions-compliant.
  • Exhaust compatibility: this downpipe connects to the stock exhaust line.

Why choose Milltek Sport?

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