Looking for an exhaust for the 250EX build. Local shop has a bunch of dumb asses saying that HMF does not offer a full system. Trying to get me to buy the FMF Powercore4 slip-on. Is this pipe any good? They can have it tomorrow $215. Was wanting the HMF full system, but they say they cannot find it. I know I can order it off of ebay $289. I know the best pipe for the bike is the Pro Circuit full system, but I don't want to pay $500. The bike is for my girlfriend's son. He thinks it's just getting new rings and a tune-up.lol Anyone have any suggestions?
