man i dont know if you guys are still watching this thread, but i had the alba pipe kit and it sucked! damn spark arrester bolts stripped out and broke off in the pipe. and if you need any replacement parts, good luck finding any. alba doesnt make any because... they dont make their pipes! i tried to get a new core from them and the guy acted like he didnt know what i was talking about. he didnt know who made them either. best bet is a company that makes their pipes and makes replacement parts, like HMF and FMF (my preference). also, kinda pissed with alba since the jetting that came with the kit that was on my quad when i got it was way off. apparently the jetting had to be stepped down 15 stages! pretty crappy. dont know for sure if it was the alba jet kit or something some dumbass put in it, but it sucked down gas like a cheap whore for only having a pipe and K&N (back then). i know im probably a little late on this thread, but just thought i would throw my 2 cents in. later
