The f82 M4, with a 3.0l twin turbo, inline 6 cylinder engine producing from 425 to 493hp, is a worthy successor to the M3 legacy. As with all turbo induction engines, the potential to improve the sound, and power response through exhaust tuning is substantial!
Kline felt that the factory BMW exhaust was not special enough, it does not live up to the raw nature of the supercar. The basic Kline sound requirement was to create something that would truly scream at high revs, while being almost stock quiet at cruising speeds.
Under valve closure, the exhaust gasses are diverted through a series of chambers and acoustic sections to completely remove any drone. At valve open, the exhaust becomes completely free flow for optimum performance and sound, the gasses only passing through our trademark tight radius x pipe, to effectively raise the pitch of the exhaust note. The exhaust note on valve open is seriously incendiary; the x pipe raises the pitch of the exhaust note into a raucous aggressive vocal for that “demon screaming” sound!
