Frequently asked questions

• Is an ECU tune required? Yes. A suitable ECU map (Stage 2) is essential to get the full benefit of the gain and avoid a check engine 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 real emissions control while letting through much more flow than the original. It is the choice of tuners who want to keep a vehicle clean.

Why choose Milltek Sport?

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