Most Frequently Asked Questions

• Highway drone? It is the number one concern on forums. This version keeps a resonator (resonated): the sound stays full under acceleration, while the system remains mellow at steady cruising speed, ideal for everyday driving.
• Homologation: this system is ECE / EC homologated, a real plus for driving with peace of mind and passing the technical inspection.
• Installation: the system uses the original mounting points. A shop with the right equipment typically fits it in one to two hours.

Why choose Milltek Sport?

Milltek Sport designs and manufactures its exhaust systems in England, using mandrel-bent tubing to preserve the inner diameter and a fit developed on the actual vehicle. The result: a clean installation with no modifications required, and a sound tuned to remain pleasant for everyday driving.
