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 100cpsi, 200cpsi, 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.
Being a turbo car, the potential for increasing performance via exhaust and software is huge. The largest gains with our De-cat system are 40hp and 64nm. In conjunction with software we achieve 70hp and 94nm.100cpsi and 200cpsi produce smaller gains of 21hp and 16hp respectively.
