Are there any other exhaust that put out that much power? I would rather have the power than have the sound and looks..Any suggestions?
the kazuma has claimed 20hp gains. loud as hell though. but you said that you dont care about looks or sound... oh yeah, its not exactly legal, so you are gonna have to be careful about not redlining and making noise if there is any chance that the po-pos could be around.
its your best bet if you want a lot of power (as long as you can control your revving)
