Save your money and gut your stock pipes. You'll have as good of sound volume and performance as with any pipe that you pay 600 or 700 bucks for. The built in reducer for the right amount of back pressure and you don't have to jet up as much to get that fuel mixture just right.



I agree except for the jetting, most very free after market pipes come with about a 155 or 160, I run gutted stock pipes with K&N pods on the carbs, I left the reducer cone in for back pressure and I run 155 mains and 48 pilots and the dyno says I am just about right, little rich down low but not by much I think I may keep the 48s now, I was going to go 45 but I think I took care of it with the mixture screws.

As for performance I agree that gutted stock is as good or better than most after market pipes for sound and performance, can't say thats true for all. Sound maybe since I really love the sound of mine but I'm sure that if nothing else Super Trapp is better from a performance stand point.

I learned all I need to know about life by killing smart people and eating their brains.
