Most frequently asked questions

• Is a remap required? Yes. An adapted ECU map (Stage 2) is essential to realize the gains and avoid a check engine light linked to the lambda sensors. It is the most frequently asked question from buyers, 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.
• System compatibility: this downpipe is designed to connect to a Milltek exhaust. Check for the version suited to your setup if you keep the factory exhaust.

Why choose Milltek Sport?

What comes up most often in customer feedback: the fit quality and a deep sound, present but never harsh. This is the signature of Milltek Sport, a British manufacturer specializing in stainless steel exhausts.
