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 a slight drone that can appear at certain engine speeds on long trips. If you do a lot of highway driving, compare it with the resonated version.
  • And the neighbors in the morning? The valves are controlled as on the original: system closed and discreet on startup or in comfort mode, fully open in sport mode.
  • Installation: fitting requires cutting the original exhaust. We recommend having a professional handle the installation.

Why choose Milltek Sport?
