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.
