The GT2, the pinnacle of the 997 range. the factory setup incorporates a titanium rear silencer section, so how could we improve on this? simply upgrading the material to formula one grade Inconel 625, the removal of the center chamber, addition of our trademark tight radius x pipe, and upgrading the catalyst section for 100cpsi HJS units, or decat sections for optimum performance.
The Factory setup produces the most lackluster sound, mainly due to a series of chambers, restrictive catalysts, and the most prominent flaw being the lack of balance between opposing banks. Replacing the stock cats for either 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 Innovation.
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.
