Most frequently asked questions

  • Is a remap required? Yes. An adapted map (Stage 2) is essential to get the gain and avoid a check engine light linked to the lambda sensors. It's the most common question from buyers, and the answer is always the same.
  • 200-cell sport catalytic converter: it keeps real emissions control while flowing much more than the original. It's the choice of tuners who want to keep a clean vehicle.
  • Exhaust compatibility: this downpipe is designed to connect to a Milltek exhaust. Check the version suited to your vehicle if you keep the original exhaust.

Why choose Milltek Sport?

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