[stockboy]

looking for a new pipe dont care how loud it is i just want to know what pipe has the best performance increases

i have the full big gun race series exhaust, it's really loud. I like it!! But I wouldn't know which one gives the best performance.

how about i change the question does anyone know how much hp their pipe adds?

Ic why you changed the question haha. I dont think many people try different pipes. The problem with the second question, usually people do a few mods at the same time and if they even run the quad on a dyno people dont know exactly.

Can't say about horsepower, but I run a Sparks pipe, loud and seemed to add a noticeable amount of power.
