You want your quad to RIP??
unscrew the gas cap, put a banshee under, put the gas cap on. Now it will rip. For real.
hehe.

 

i run a 150 with my white bros pipe and kn filter....im getting my quad built now but it ran awesome with that +1 main jet...white bros suggest not to mess with jetting that much, if any...there pipes are already set for your quads stock jetting, but of course due to elevation it will vary...i live in northcarolina and run 150 and it doesnt back fire smoke or anything, just hauls @ss!!!!!

 

Yeah stock jetting is usually a little rich,the muffler should make it just right.
