I know it will kill the power a bit but I currently have an old White Bros E series. I have repacked it and installed a quiet baffle and am still at 98dB. In order to participate in an upcoming race I need to be under 96. I have recently done a ton of work to my bike ($$$$) and cannot afford the Q pipe and the power bomb before then. This is a cheap way to go to give cross country racing a try. Hopefully it won't be too bad on power. :)
