What it feels and sounds like

With valves closed, refinement is maintained for daily use. Open the valves and the S58 comes alive with a hard-edged, race-bred tone that’s assertive without drone. Our team has fitted this setup and the feedback from customers has been consistently positive on sound quality, finish and overall driving enjoyment.
