Our most frequently asked questions

• Highway drone? It's the number one concern on forums. This version keeps a resonator (intermediate muffler): the sound stays full under acceleration, but the line stays calm at steady speed, ideal for everyday driving.
• Fitting: the system uses the original mounting points. A workshop typically fits it in one to two hours.

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