Product Details

Starting at the drawing board, the points of improvement over the OEM design and many existing sports exhausts were reviewed. Kline’s main objectives were to increase power, remodel and accentuate the sound, and reduce half the weight of the OEM system with this Porsche 996 GT3 exhaust.

The first point that stood out, was the catalyst design. 600 cell OEM cats, and absolutely no balance present in the factory exhaust. Replacing this GT3 exhaust system for a 200 cell sports catalyst they were able to achieve some moderate power and torque gains. The second design alteration was to remodel the way in which the exhaust gases interact from opposing banks. Replacing the two piece design for a single piece with their trademark tight radius, laminar flow X pipe, they were able to alter the exhaust pitch, and smooth out the imbalance. This resulted in a far higher revving race car-like sound. This was a Porsche 996 GT3 exhaust system design innovated and pioneered by Kline.

The factory silencers, heavy, cumbersome, and restrictively chambered, produce a tinny note to the exhaust. Kline needed to enrich the sound, as well as improve gas transit, and simultaneously reduce weight. Weight reduction and sound enrichment proved to be fairly straightforward with the simplification of the silencer design and removal of the multiple chambers. The addition of a single chamber volumetrically tuned towards low rev resonance, removed bass noise at cruising speeds, while a rich raucous vocal is achieved at hard throttle above 4000rpm.
