Frequently asked questions

• Highway drone? It is the number one concern on forums. This version keeps an intermediate muffler (resonated): the sound stays full under acceleration, while the exhaust remains calm at steady cruising speed, ideal for daily driving.
• What about the neighbors in the morning? The valves are controlled as on the original system: closed and quiet on startup or in comfort mode, fully open in sport mode.
• Homologation: this exhaust is ECE / EC homologated, a real advantage for driving with peace of mind and passing the technical inspection.
• Fitting: the system uses the original mounting points. A equipped repair shop typically fits it in one to two hours.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, using mandrel-bent tubing to preserve the internal diameter and a fit developed on the vehicle. Result: a clean installation, no modification required, and a sound tuned to remain pleasant for daily use.
