I have a 2007 ultra classic. I am wanting to put on the Vance and Hines basic slip on mufflers. Has anyone put these on? If so did you have to remap or anything else to the bike? Thanks

I don't get why adding free flow exhaust and less restrictive air cleaner would kill your mileage. That makes no sense assuming you are riding it about the same way.
I wonder if that fuel module is running too rich?
Are your pipes black inside?
What do your plugs look like?
I did a 95 inch kit on my '04 Classic with 203 cams, slip ons, K&N air cleaner and Teclusion module a few years back, and I don't think I lost any mileage at all.
