im looking for a good to great pipe and silencer for my 2000 KX 500. Money is not the issue becouse ive finally saved enough money from the wife that its time to buy(MAN STASH)....Ive looked at the pro circuit platinum and plt 2 and also the work pipe. For the silencer the R304 and the 304. If its not one of those thats fine. I do alot of open rideing in Attica, IN (Badlands). I was just wandering if anybody had any good ideas for me. Thanks for all the help.....go #2 in the supercross series!!!!!
