Got my new pipes from Chevy605 on Ebay. I figured before I shell out $500 bucks I would try these. He had them listed as $195 or best offer. I shot him one. I won't say what it was, but it was less than $195. Anyway, got them on the bike yesterday. They rock. They are a set of TOR's that have been modified. They're loud and throaty, but not too loud to wake up the neighbors. He charges $80 for core replacement. I have send my stock pipes back to him. I haven't decided whether to do that.
