Our most frequently asked questions

• Is an ECU remap required? Yes. A suitable Stage 2 map is essential to make use of the gain and avoid an engine warning light related to the lambda sensors. It is the question buyers ask most, and the answer is always the same.
• And the technical inspection? A decat downpipe does not pass the emissions test. This product is intended for motorsport use only.
