I have them on my 2013 switchback and I have had them on since last July. Though they have a good sound, I always thought they were alittle too quiet, especially when I am being told it sounds like a mean Honda..LOL
I pulled out the baffles yesterday and holy crap, it's like I have a whole new exhaust. Rode it about 200miles and it sounds like I think it was made to sound. Deep but not obnoxiously loud. I didn't notice a thing in performance, if there was some low end loss, it was so minor I couldn't really tell.

 

Glad to hear you say it sounds good. I am trying to get my baffles out and am curious how you got them out? I am having a hellava time!! Got one most of the way out but the other on won't seem to budge. I even let the bike run for about 5 minute thinking the heat would help but it didnt seem to!?!? Any suggestions? ?
