Frequently asked questions

• Is ECU tuning required? Yes. A matching ECU map (Stage 2) is essential to get the gain and avoid a check engine light linked to the lambda sensors. This is the question buyers ask most often, and the answer is always the same.
• What about the technical inspection? A decat downpipe will not pass the emissions test. This product is intended for motorsport use only.
• Exhaust line compatibility: this downpipe connects to the stock exhaust line.
