Frequently asked questions

• Highway drone? That is the number one concern on forums. This version keeps a resonator: the tone stays full under acceleration, while the exhaust stays quiet at steady cruising speed, ideal for everyday driving.
• No valves: the exhaust is always active. On a vehicle with factory valves, a valve delete module may be needed to avoid a warning light (see fitting information).
• Homologation: this exhaust is ECE / EC approved, a real plus for driving with peace of mind and passing the contrôle technique.
• Fitting: the exhaust uses the original mounting points. A workshop typically fits it in one to two hours.

Why choose Milltek Sport?

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