The benefits are 3 fold, you can pass emissions with ease, you don?t need to run a software file (for those who are concerned about warranty) and you have a beautiful sounding system. _x000B__x000B_But we didn?t stop there; our system also makes substantial power without drone!! We noted a + 15 crank hp & + 14 crank torque gain, predominantly in the mid and top end. The increase in mass and velocity of exhaust flow through the specially built muffler internals produces a strong, linear, firing-order dominated true flat-6 PorscheÆ sound. _x000B__x000B_This system retains the factory vacuum lines so that you can select the sound you want. It is factory quiet with the valves closed and far more aggressive with deep, rich tones with the valves open. _x000B__x000B_In addition, each of our exhaust products have been extensively tested on both a chassis and engine dyno as well as logged thousands of miles on both the street and at the track. All this research, development and testing ensures maximum horsepower gains throughout a broad power band; all while maintaining reasonable sound levels for the street and provide a distinct, sporty exhaust note that is purely PorscheÆ._x000B__x000B_Please Note: For vehicles without factory Exhaust System with valves, order Electronic Control kit (Our part # BES KLS 000 001) separately._x000B__x000B_
