i have a 2003 VTX 1300S, found a set of black 3" hard krome drag pipes, just what im looking for, but the ad says they are for 08-09 models...is there a diferrence between the '03-'07 and the '08-'09? i thought there wasnt, because i always see ads for V&H big shots that say fits '03-'09...why the conflicting ads? can anyone clarify? thanks!!!
