2008 flhtcu, amsoil 20/50,hd+,spectro 6-spd, thanks to help on this site. Now i'm ready for stg 1 : se a/c with k&n filter,tfi (gen 2 ?) and not sure which slip-ons yet. My question is say I go with Rush, is there a performance differance from 1.5" to 2", do 2" breath easier? Would it differ enough to notice? Also with a crossover does the left/rear scavange side get a larger or smaller baffle? Great forum, thanks to all
