I bought this bike already set up :>) and a fine job! but I keep hearing about the burly rev pipe? well mine has has a gnarly pipe on it, it must be a rev pipe because this thing never stops reving! I have a dennis kirk in the libary with a cordless phone handy. and I've spent my far share of $$$$ in there. but I've never seen a gnarly pipe in there catalog? so I ask spud #2 the kid knows every thing "right" he says its just a older model of the burly pipe and yes dad its a rev pipe. is he right ?
