Are you using the cat headers or catless headers?

I just used catless headers and the volume went up considerable.
Just right for me. I can still hear my tunes rather good.

Even the CVO mufflers on the left side is restricted.
Does the fullsac help with that?

Just a thought.

I just ordered a set of 1-3/4" CVO cores with the sleeves for my 2012 CVO RG, I wanted to stay with the stock mufflers since the 110 is pretty fast almost as good as my stage 4 103 pushing 124/121, but a lot smoother and is under warranty.
I am going to try something a little different this time with the CVO cores, I have a set of stepped 2:1:2 2" headers from my Megashots, Im going to open my muffler inlets to fit into the 2" headers, then install the Fullsac and get a proper tune. I think that's going to give a great flowing and hopefully sounding exhaust. (In case this didn't work I have a spare set of CVO mufflers to work with.)

I used Fullsac 2.25 Powercores in the CVO mufflers off my 2013 FLHRSE5. I decatted the stock headpipe by cutting a window out and polished the inside of the collector. I used the screens that Steve reccomends with the powercores and did as he suggested by using the packing material out of the left muffler in both, using half of it in each. This exhaust system reacted great with my TTS & Dyno Tune! Bill at Woods Performance Tuning was able to find 96.42 HP & 116.49 TQ on this otherwise stock 110. IMO it sounds great. The bike runs even better. I am a happy camper with this setup! No further engine mods needed.

The Fullsac 1.75" cores are just slightly louder then stock HD pipes. The best selling cores from Steve @ Fullsac are the 2.0" cores for both performance and sound.
However, the CVO power cores (every size) will get a bit louder with some time.

I have two sets from Steve. The 2.25" and the 2.50" power cores. The 2.25" cores are all around prefect for me and the BSR.
The 2.50" cores are the loudest and do allow some car alarms to go off, but nothing like back in 2009 when I had V&H Dressers & Rineharts racing pipes! Car alarms would go off two blocks away from me!!!

I was among the first that Steve sent 2.50" power cores to. Since putting them on, they have stayed on! But the nice things is, if I want to swap out, there's nothing to it.

I had a set of 2013 CVO slips that I put the quiet baffles in. If you just take some of the packing out what will happen is that it will shift around. Fullsac has a screen thing to hold the packing in place so you use half of what's in the stock slip. That's the route I went. Oh and I used packing material that is used on industrial generators to get the sound nice and deep.
Oh they are for sale for $200 shipped. 2013 CVO slips with FS quiet baffles in gd Cond

I just re-cored a set of CVO mufflers off of a 2012 CVO Ultra with 2" Fullsac cores. And despite what some people say, they did not have any screens in them holding the packing off the stock baffle when I took them apart. I did get the perforated screens from Fullsac and reassembled them using 1/2" TECHMAT muffler packing that I bought off of ebay. A sheet of 1/2" x 20" x 38" was shipped for about $30 to my house from the seller in North Carolina. Haven't put them on the bike yet, so I can't tell you the sound quality.

2012 CVO muffs

I too re-cored a set of CVO 4" mufflers with 2" Fullsac cores and used the screens that Fullsac sells. I re-stuffed them using 1/2 the original packing around the screens. Installed the muff's on my 09 Ultra. With the 2" cores and the screens installed, the performance dropped off immediately and dramatically, having to use full throttle just to get onto the freeway. Took the Fullsac cores back out and put the stock ones back in and things were better. The sound not quite where I wanted it, but I lived with it for a while. Started reading some of the other posts about exhaust flow restriction due to not having ENOUGH packing, so I ordered two packages of 1" x 12" x 24" muffler packing sold by ThermalZero. Theirs is made of a ceramic material that supposedly holds up to heat three times better than fiberglass. Anyway, I pulled the screens and old packing out. The old packing was completely disintegrated in one large spot in one of the muff's, which created a hot spot and blued the chrome. Re-packed the cores tight with the ceramic material and stuffed it all back in. Was a little tough to get it all in there, but used some Scotch tape to hold it together long enough to get them stuffed. The tape should burn away quickly. Cranked it up and took it for a ride and the packing made a HUGE difference in both the performance and sound quality. Next step is the intake and PC-V.
