just picked up a 02 426 that dual sport converted, but i want more power... all it has is a jd jet kit and bk mod... would both power nows, a quickshot or p-38 cover, and a fmf powerbomb header fill my need for boost? also, whats the best sounding race exhaust for the 426? was thinking the stocker sounds pretty good...and probally only need the powerbomb header mated to the stock can... but maybe a good shorty ti can for the powerbomb header would do the trick... anyone???
