Most frequently asked questions

• Is an ECU remap required? Yes. A suitable Stage 2 ECU map is essential to make the most of the gain and avoid an engine warning light linked to the lambda sensors. This is the question buyers ask most often, and the answer is always the same.
• What about technical inspection? A decat downpipe does not pass the emissions inspection. This product is intended for motorsport use only.
• Line compatibility: this downpipe connects to the OE exhaust line.
