Ferrari 458 Speciale Exhaust<\/h1>\n<\/div>\n

The Ferrari 458 has become the benchmark against which all modern supercars ar compared, the speciale being the highest performing model. Here at kline we decided to build the ultimate exhaust system. Our usual criteria was to create an exhaust of unparalleled performance, sound, and lightness.<\/p>\n

The Sound<\/h4>\n

Here at Kline, we felt that the Factory exhaust for the 458 speciale did not reflect the true beauty of this stunning supercar, or reach the full sonic potential of the 4.5 liter V8<\/p>\n

Starting at the drawing board, the first aspect to be upgraded, replacing the stock catalysts for high performance 100cpsi race catalysts, thus reducing the gas drag coefficient, and improving scavenge, and ultimately torque response and peak power figures.Replacing the heavy, cumbersome, built down to a cost factory silencers, for our harmonically tuned silencers, we were able to enrich both bass and treble frequencies, as well as significantly reducing weight. The final, and perhaps one of the most important design features, unique to Kline. Our trademark tight radius laminar flow x pipe. The resulting sound is unbelievably smooth under light driving conditions, and a howling raucious high pitched incendiary vocal when you need it.<\/p>\n

Under low revs (valve closure) the gases are allowed to pass through a chamber, and an acoustic ceramic filled silencer, with the cross sections tuned toward reaching optimum gas velocity for achieving maximum torque. under hard load and high revs, the valves open for optimum power.<\/p>\n","protected":false},"excerpt":{"rendered":"
