THE SOUND
Kline Innovation systems are tuned for a raw, high pitched motorsport sound without the drone. On valve open the exhaust gases take a completely free flowing path for maximum sound, and on valve closed they pass through a harmonically tuned silencer that keeps the car civilized when cruising. Kline's signature tight radius X-pipe geometry raises the pitch of the exhaust without restricting flow, and the thin wall Inconel 625 resonates to produce an even higher pitched scream at high rpm.
MATERIALS
Every system is offered in 304 grade stainless steel or F1 grade Inconel 625 superalloy. Inconel 625 is the same material used in Formula 1 exhausts: it holds its strength at extreme temperatures, allows a much thinner wall, and saves significant weight over stainless, while adding its own distinctive sound character.
