I have a buddy that has offered me all of the stuff he took off of his rzr. Everything still looks new and is about 3 months old. He has a K&N air filter (which I will never run because they are junk) A Procom programmable ECU, a primary clutch red spring and weights, and an iti stainless 2 into 1 exhaust. I know what the filter, ECU, and clutch parts are worth, but I cannot find anything about the iti company at all. I found an old website that doesn't work and a few forums with dead threads, so there is absolutely no info on this exhaust system anywhere. He wants $600 for everything, but the exhaust is all I would use because I already have all the other stuff, but the ECU I can sell for $150 and the clutch parts for about $50, so I will esentially have $400 in this exhaust. I know $400 isn't alot of money, but I don't want $400 worth of scrap metal laying around my shop!!! Any input would be greatly appreciated, has anyone on here ever ran these, heard them, or know anyone who has?
