I recently installed FullSac 2-1-2 and already had CFR Slip ons. They are way to loud for me! Has anyone used the Fullsac CVO muffler inserts.

I was thinking specifically the 2 inch size.

 

The bigger diameter tube the louder it gets. No experience with the full sac but the 2 will certainly be quieter.

 

Making multiple threads for the same thing don’t help.

I used the cvo with 2” cores on my 16 rg, now have the same muffs on my 20 triglide. I tried the 1.75 didn’t like them. 2” are pretty well balanced for a 114 motor. Worked ok with the 107 HO motor. Going with a 2.25 baffle might be a bit much unless you do some motor work.
