I am thinking about getting a yoshi full pipe off a guy on here and Im wondering one thing...Can I put the pipe on, plug in my cherry bomb(when it gets here) take the airbox lid off, and be completely fine? If I need to buy one of those "map" things then forget it, I will just remove the pea-shooter from the stock pipe, and ride it like that. For those of you that had the stock pipe(when you first bought it obviously) and have since put on a yoshi, is there a real difference or not? If removing the pea shooter will give it the same sound and SOMEWHAT the same gains in power, I will just keep my money, and spend it on other goodies for it(nerfs,bars,bumper...) Thanks a lot guys, I just dont want to waste my money!
