Most frequently asked questions

• Is an ECU remap required? Yes. A suitable Stage 2 map is essential to get the gain and avoid an engine warning light linked to the lambda sensors. It is the question buyers ask most often, and the answer is always the same.
• 200-cell high-flow catalytic converter: it maintains real emissions control while flowing much more than the original. It is the choice of tuners who want to keep a vehicle clean.
• Line compatibility: this downpipe is designed to connect to a Milltek line. Check the version suited to your setup if you keep the original line.
