I have read the post about slip ons on here (which specifically mentioned WG's and touring). I have an 08 Dyna Low Rider...my local HD shop told a buddy of mine that slip ons can be added with no mods. True or not true? I want to do full exhausts at some point...but if I can do slip ons for now then I will wait to pay the 1600 for exhaust work until after I get some other things done that I want. The stock exhaust sound is driving me nuts!!!
