Frequently asked questions

• Is an ECU remap required? Yes. A suitable ECU map (Stage 2) is essential to make the most of the 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.
• What about the contrôle technique? 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 system.

Why choose Milltek Sport?

The feedback we hear most often from customers: fit quality and a deep tone that is present but never harsh. This is the signature of Milltek Sport, a British manufacturer specializing in stainless steel exhausts.
