Most frequently asked questions

• Droning on the highway? This is the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, while the system remains unobtrusive at steady cruising speed, ideal for daily driving.
• Valveless: the exhaust sounds at all times. On a vehicle with factory valves, a valve delete kit may be needed to avoid a warning light (see fitment information).
• Installation: the system uses the original mounting points. A properly equipped repair shop usually fits it in one to two hours.

Why choose Milltek Sport?

What owners most often point out in reviews: the quality of fit and a deep tone, present but never harsh. That is the hallmark of Milltek Sport, the British specialist in stainless steel exhausts.
