Our most frequently asked questions

• Is an ECU remap required? Yes. A suitable Stage 2 ECU map is essential to get the gain and avoid a warning light linked to the lambda sensors. It is the most frequently asked question from buyers, and the answer is always the same.
• High-flow catalytic converter (200 cells): it retains genuine emissions control while flowing considerably more than the factory unit. It is the choice of tuners who want to keep the vehicle clean.
• Line compatibility: this downpipe connects to the factory exhaust line.
