Most frequently asked questions

• Is an ECU remap required? Yes. A suitable Stage 2 ECU map is essential to get the gains 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.
• What about the technical inspection? A decat downpipe will not pass the emissions test. This product is intended for motorsport use only.
• Exhaust compatibility: this downpipe is designed to connect to a Milltek exhaust system. Check the correct version if you keep the original exhaust.

Why choose Milltek Sport?

Customer feedback most often highlights the fit quality and a deep tone that is present but never harsh. This is the Milltek Sport signature, from a British manufacturer specialized in stainless steel exhausts.
