is the corsa exhaust only fit for a bike that has motor work done to it? i've heard that it's too wide a diameter for a stock motor and the sbk stainless exhaust would be better for a stock (minor mods) motor.
I spoke to Leo Vince just last week and was told the same thing. The rep said that the corsa system is really more designed for superbike or formula extreme motors, and that the regular sbk stainless exhaust is better for a superstock/supersport motor. There is a difference in the diameter of the header pipes.
