Our most frequently asked questions

• Is a remap required? Yes. A suitable Stage 2 map is essential to get the full gain and avoid a check engine light linked to the lambda sensors. It is the question buyers ask most often, and the answer is always the same.
• What about the French technical inspection? A decat downpipe will not pass the emissions test. This product is intended for motorsport use only.
• Line compatibility: this downpipe is designed to connect to a Milltek line. Check the correct version if you keep the factory line.
