Hello, I just bought a 99 scrambler 500 and have a few questions. First can anyone recommend either a exhaust slip-on or full system? I have seen good reviews for a HDP pipe and FMF slip on but have heard problems of durability with the HDP. Secondly has anyone else had problems findings replacement stock size rims for this quad? I can't find black stock size rims for the life of me. I was thinking of jumping up to 12in rims but am not sure of any problems that could arise from that. Also welcoming any opinions on Kenda bear claws or just replacing the titan at489's on the machine. Any help much appreciated!
