Most frequently asked questions

• Is an ECU tune required? Yes. A suitable ECU map (Stage 2) is essential to get the full gain and avoid an engine warning light linked to the lambda sensors. It is the question buyers ask most often, and the answer is always the same.
• 200-cell high-flow catalytic converter: it keeps genuine emissions control while flowing considerably more than the original. It is the choice of tuners who want to keep the vehicle emissions-compliant.

What customers mention most often in their feedback: fit quality and a deep tone, present but never harsh. This is the signature of Milltek Sport, a British manufacturer specializing in stainless steel exhausts.
