997 GT2 Exhaust

The Sound

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.

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.
