997 TURBO GEN II

The 997 turbo being our primary marque, we wanted to apply the same design innovations, and perfect sound to the Gen II . After reviewing the factory exhaust, major flaws were pinpointed in all areas of the design. Kline designed the worlds first gen II equal length manifolds significantly improving turbo spool, torque curves and peak power. Added to this our  usual uncompromising standards in exhaust design and manufacture and sound enhancement.

THE SOUND

The Factory setup produces the most lackluster sound, mainly due to a series of chambers, 600 cell catalysts, and the most prominent flaw being the lack of balance between opposing banks. Seriously, i would recommend when considering any aftermarket exhaust for a Porsche turbo, never buy an exhaust without some kind of gas balance between left and right banks. replacing the stock cats for a choice of 200cpsi, 100cpsi, or de-cat increases the sound respectively. Replacing the chambered transverse rear silencer with freeflow harmonically tuned silencers enriches the sound, and the addition of our trademark 1D CLR laminar flow X pipe raises the exhaust pitch beyond the region in which bass noise is able to penetrate the cabin, while under hard throttle and high revs, a rich and raucious vocal ensues. This design was pioneered and innovated by Kline, however several copycat designs have started to appear.

PERFORMANCE

Being a turbo car, the potential for increasing performance via exhaust and software is huge. The largest gains with our De-cat system are 42hp and 50lb/ft. In conjunction with software we achieve 75hp and 74lb/ft.

addition of Kline equal length manifolds increases the rate of turbo spool, and the addition of an extra 12lb/ft torque, and 9hp.
