Sound level Milltek sound levels
  • Standard exhaust Your car as it left the factory: one bar.
  • Resonated Keeps a centre resonator: deeper and more refined, with the least motorway drone. Most EC-approved systems are Resonated.
  • Road+ A step up from Resonated: more presence, still made for everyday driving.
  • Non-Resonated No centre resonator: noticeably louder and more aggressive, especially under load.
  • Race The loudest, built for maximum flow and track days. Not EC approved.
Milltek don't publish decibel figures, so the bars show each level's order, not exact volume. Every level is louder than the standard exhaust.

Milltek make this exhaust in 3 sound levels for your car. Each is a separate exhaust: tap another level to see it.
