Hi to all, I certainly appreciate all the good info on this site. I have installed the fullsac 1.75 baffles in my 09 SEUC. But I was wondering if any one has removed their stock baffles, drilled a bunch of 1/8 inch holes in them, and reinstalled them. Once they are removed you could drill a hold in the flange at the end and drill a hole in your muffler like you have to do with the aftermarket baffles and put them back in. Who knows, with the fiberglass packing in there they might sound pretty good. I have modified some baffles for my 95 Heritage to get rid of the barking by increasing the size of the existing holes to 1/8 inch  and the sound seemed to be more mellow. Just a thought to save someone some money. CAHDBIKER

I have been considering doing just that. I am running Fullsac 2" baffles and don't think going to 1.75" is going to do the trick for me. Hence, I am considering playing with the stock baffles, or wrapping the 2" Fullsacs with a layer of material, and seeing if I can get them back in with the stock packing and screen still in place in the CVO cans. I figure the additional packing can't blow out due to the 'partition' on the outlet of the baffle. I had a set of CFRs, and any packing on an additional baffle on the inlet last about 1 minute.
I want something a bit quieter that isn't going to radically kill the engine mods I've had done. In addition, I am not exactly enamoured with the sound at idle now. Friends of mine agree with me on the idle 'sound', but say it sounds great at speed.
As far as mods to the stock baffles go, I don't really know where to start. I'm thinking you don't want to create too little back pressure by overdriiling, but want to introduce a little more 'relief' towards the sleeve of packing on the perimeter to quiet them down a bit.

Zipper,If I was going to do it I would start with no bigger than 1/8th inch holes completely around the baffle (it will take about 5 or 6) starting at one  end and spacing them out in rows about one inch apart. You can always go bigger or add more holes if you want to. If you do it let me know. CAHDBIKER
