Re-Tune
I have a 2009 Ultra with 108,500 miles,S&S 551 cams,SE a/c,Rush true duals,Jackpot dyno-tuned mufflers. Muffs are too loud,would going to CVO muffs affect the dyno tune(sert) that I already have had done by the Dealer?
Thanks for your help!

When you get down to splitting hairs just about any component change will make some difference, but I would not retune just swapping mufflers. Any difference should be negligible and unless the bike runs noticeably worse I'd let it be. If it was cams that would be a different story.

You've got a lot of fuel being fed into that motor which makes the exhaust louder. Proceed with caution or your going to go through a lot of cash. See if there's a quieter baffle you can put in those pipes.
