Description
Starting at the drawing board, the points of improvement over the oem and many existing sports exhausts were reviewed. our main objectives, increase power, remodel and accentuate the sound, and half the weight.
The Sound:
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 unit for a 200 or 100 cell sports catalyst we 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 our trademark tight radius, laminar flow X pipe, we were able to alter the exhaust pitch, and smooth out the imbalance, this resulted in a far more high revving race car like sound.
The factory silencers, heavy, cumbersome, and restrictively chambered, produce a tinny note to the exhaust. We 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 volumetricaly tuned towards low rev resonance, removed bass noise at cruising speeds, while a rich raucious vocal is achieved at hard throttle above 4000rpm
