Installed this combination on 2011 Ultra Classic and it sounds like crap. Very loud and high pitched on top of that. Sounds like some of the Wanna be's I have heard. Not sure what to do now. A bunch of cash spent and I hate to start over. Any suggestions would help.
Change out the Vance and Hines to either the American Custom " catless" headers or the FuelMoto " catless" headers. The American Custom's are only $ 299.00. This is what I have.
4" Rineharts with catless oem headpipe, Xieds, Airlen Ness Big Sucker Air Cleaner, Stage 1 Download. Nice sound, not too loud, low rumble at idle, she will talk to you if you get on it.
Never had trouble with decel popping or baffles that rattle.
+1 on the 3.5 and stock 09 head pipe. I have liked them since I heard them. Debating on upgrading to the 4". A couple friends have the 4" and they sound as good but a bit deeper. Not too loud on highway crusing, but do let you know I am there if I get on it.
