The Porsche 992 GT3, the latest in the line of track orientated 911's. with its 4 liter flat 6 boxer engine producing 503hp at 8400 rpm, and its new aluminium and steel chassis, this is a thorougbred supercar. the exhaust however, stifled by manufacturing sound and emission restrictions, could do with a little sonic makeover.

THE SOUND: The first aspect of the stock exhaust that really holds the sound back, is the 600cpsi catalysts, and OPF filter, removal of these, and the addition of HJS high flow race catalysts, or our long tube header with decat design, opens the sound up significantly. the gases then pass through one of two transits in the silencer section. On valve open the transit is completey freeflow for maximum sound, on valve closed, the gasses pass through our harmonically tuned silencer to remove cruising drone. Addition of our signature tight radius x pipe raises the pitch of the exhaust significantly into a raucous, yet beautiful, incindiary scream, without causing any restriction to the gas transit. The material Inconel 625 also has a unique sound, further enhancing the natural charachteristic sound of the kline system. The sidewall is very thin, and resonates to produce an even higher pitched scream at high revs.

PERFORMANCE: The largest performance gain comes from replacing the catalysts and OPF filter in the stock headers. The Kline headers and silencer section are designed to work in conjunction with eachother for optimum performance and sound. The Kline system and headers are available in 2 options, 100 cpsi catalysts producing a largest gain of 25 hp and 32nm, or decat long tube headers producing a largest gain of 31hp and 38nm
