Our most frequently asked questions

• Highway drone? It's the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, but the exhaust stays unobtrusive at steady cruising speed, ideal for daily driving.
• And the neighbors in the morning? The valves are controlled as on the factory system: exhaust closed and discreet on cold start or in comfort mode, fully open in sport mode.
• Homologation: this exhaust is ECE / EC homologated, a real plus for driving with peace of mind and passing the technical inspection.
• Fitting: the system uses the original mounting points. A workshop with the right equipment usually fits it in one to two hours.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhausts in England, with mandrel-bent tubes to preserve the internal diameter and a fit developed on the vehicle. The result: a clean fitting, with no modifications needed, and a sound tuned to stay pleasant every day.
