Frequently asked questions

• Is a remap required? Yes. A suitable Stage 2 tune is essential to make the most of the gain and avoid a check engine light caused by the lambda sensors. This is the question buyers ask most often, and the answer is always the same.
• High-flow sport cat, 200 cells: it retains real emissions control while flowing much more than the original. It is the choice of tuners who want to keep the vehicle clean.

Why choose Milltek Sport?

What customers mention most often is the quality of fit and a deep tone that is present but never harsh. It is the Milltek Sport signature, from a British maker specialized in stainless steel exhausts.
