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.
PERFORMANCE
The largest performance gains come from replacing the restrictive factory catalysts. Kline headers and cat sections are offered with HJS 100 cell or 200 cell high flow race catalysts, or in decat form for competition use, and are designed to work together with the Kline rear section for optimum performance and sound.
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.
Decat, race and OPF delete components are sold for off road and competition use only and are not legal for use on public roads in the United States.
