Most frequently asked questions

• Resonated or non-resonated? This version is non-resonated (no resonator): it is the most expressive, with more crackle on lift-off. The trade-off is that a slight drone can appear at certain engine speeds on long trips. If you do a lot of highway driving, compare it with the resonated version.
• What about the neighbors in the morning? The valves are controlled as on the factory system: closed and discreet on startup 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: installation requires cutting the factory exhaust. We recommend having it fitted by a professional.

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 installation without modification, and a sound tuned to remain pleasant for daily driving.
