CVO muffler question?
I have a 2007 Road King that had Rush mufflers and I loved the sound but unfortunately I could not get rid of the aggravating decel popping. Even after a dyno tune and finding absolutely no exhaust leaks, I reinstalled my stock mufflers. Now, no more decel popping, but now too quite.
Has anyone tried a 2010 and up CVO mufflers on a 2007 touring? My understanding is that Harley opened up these mufflers to compensate for the CATS installed in the header pipes. Wondering how much louder a 2010 CVO muffler would be compared to the standard Road King muffler?

It seemed to me the 2011 stock pipes had a little more tone to them than other stock ones.
Without a doubt the stock ones on my 2016 do. Nice thing is Most dealers have stock ones laying around you can get them cheap or free if you on good terms.
When I traded in my 2013 I left the pipes on it. ask dealer if they wanted the stock ones, he laughed , no I have a pipe of them.
Pipes on the CVO are standard Screaming Eagle pipes.

the cvo mufflers are a great option. especially if you remove the baffles and replace them with the fullsac cvo recores.
you end up with a great looking, great sounding, inexpensive, well performing set of mufflers.
i went this route on the wife's bike. she wasn't sure what she wanted, so to get something for the 'short term' we put a set on her bike. that was over 2 years ago, and she isn't looking.

Even though you re-installed the OEM mufflers the decel popping is still there, you just can no longer hear it. The standard CVO mufflers will be just marginally louder than the stockers because of the EPA guidlines.

I put a set of SE mufflers that are EPA compliant for 10-later (cat in head pipe) on an 08 with no cat. Side by side with a bike with cat is noticeable difference. I've gotten lots of complements and neighbors haven't complained.

correct me if I am wrong but... the guy doing the tune... doesn't have to adjust every frame in the AFR window to get the outright maximum possible curve. he can adj the AFR so that decel popping is minimized or eliminated altogether.

So that's why I'm thinking a set of 2010 and later CVO's might give me a little louder pipe with no decel popping for little money.

My tuner said he did everything he could to eliminate the decel popping including leaning and enriching AFR. He said it has to be my Rush mufflers. I have my doubts but I'm into his "tune" to over $650 considering the original dyno tune and follow up session. I'd like to get a set of mufflers similar sound to the Rush .175 baffled I have, but don't want to keep throwing money at it if I'm back to decel popping! BTW, he could not find any exhaust leaks and I tried using smoke, air pressure back thru the exhaust, new clamps, copper RTV joint sealant and even soap bubbles. Nothing.

Sorry but I don't agree with your tuner. I've worked on my own SESPT Tuning Maps with the help of HDF member k5rbd... I've had True Duals and OEM De-catted head pipes running 4" Big Louies, V&H Monster Ovals and now I'm running a set of de-cored CVO's with 2" Rush Big Louie baffles installed and I have never had decel popping,,, yes I get a low grumble around 1900 rpm for 2 seconds if I down shift a couple of gears and let the engine brake the speed, but if I just let the bike slow down in 5th, 4th or 3rd gear,,, I have nothing in decel...
Maybe next spring the thought of wasting all this money will have worn off and I can start with someone new. Not easy to find someone that has experience wth dyno tunes up in my area.
