For those unhappy with their DonnyFL, "Fatboy" muffler

I've tried my Fatboy on several different guns, with little love, money fer nuthin. It actually sorta works on pistols (under 700fps). But yeah, looks a bit silly.

Messing around today, I took it apart, removed the felt or whatever the black stuff is that's wrapped around the baffle assembly.
WHAT, will work, as tested on my full length, RTI Prophet Performance I. Shooting at about 820fps.

Note - the info below was tested indoors, by ear only. No cheap, $50 gadgets, no million dollar, dB (proper way of writing the symbol) chamber and test equipment.

- The factory black (felt ?) stuff, wrapped around the baffle. Quieter than nothing, but not back yard friendly by any stretch (even at my low fps !).
- Nothing, just the big can, with a bare baffle. Not much difference than with the factory wrap material, slightly louder.
- Closed cell foam, around the baffle. Slightly...louder than the factory black wrap.
- Open cell foam, around the baffle. About the same as the factory wrap.
- Old Levi's, pant leg material, wrapped semi-tightly around the baffle. Woo, what the hell, this actually worked pretty well.

Now I can hear much more of the mechanical stuff under my ear, from the receiver, than with any of the other tests ! The sound is slightly softer also, much of the "crack" is gone.
Yes, the factory screen was and is still in place for all of the tests.

Worked pretty well in my case, give it a try if you have an old pair of Levi's (brand) laying around .
No guarantee implied !!

I did some experimenting with my fat boy a while ago. Posted what I did here. Still have it set up the same way.

 
If you do not like your fat boy I will buy it or trade a 1/2 X20 threaded Tatsu for it.
or just PM me how you want to sell it,
Mike
Mike -

Even not happy with it, I never really thought of selling it. I have a hard time selling things, especially if they are defective.
But now that it seems...to be doing its job somewhat better than it was at the original purchase time, I'll hang onto it. Probably leave it on my Prophet.

Thanks much for the offer though.

Yea, I no what you mean mike, I am not a sales man either, I just drop the price so low its gone fast, because if I have time to think about it I will take it off market. (Sellers remorse) or something like that..
I got three original fat boys from years back seem to work pretty good for me, Never taken them apart.
