Our 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 quiet on startup or in comfort mode, fully open in sport mode.
• Installation: the system uses the original mounting points. A workshop with the right equipment typically fits it in one to two hours.

Why choose Milltek Sport?

What comes up most often in user feedback: fit quality and a deep tone that is present but never harsh. That is the signature of Milltek Sport, the British stainless steel exhaust specialist.
