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 journeys. If you drive a lot on the motorway, compare it with the resonated version.
• Fitting: the system uses the original mounting points. A workshop typically fits it in one to two hours.

Why choose Milltek Sport?

What comes up most often in user feedback: the quality of fit and a deep sound that is present but never harsh. This is the Milltek Sport signature, from a British manufacturer specialized in stainless steel exhausts.
