Vance & Hines, and FMF have baffle repacking material that looks like a densely woven white fiberglass.
Has anyone tried either of these products or having any other suggestions other than normal pink house insulation ?
I want to take the bark off the MAC 2 into 1 on the XV920R.
I bought new packing material as a replacement part once.
The 2 pieces of pre-formed material was 175$ per piece, so it came to 350$ just for the exhaust packing materials. :I Won't be doing that again.
FMF works well. It's not so much the brand as it is how it's done. Too loose, and it has no sound absorption. Too tight, and the exhaust just blows right thru. Use making tape too hold it together.
Pink is a waste of time.
What about ceramic packing? Like the stuff they use in stoves. I've seen it listed on amazon as motorcycle packing curious if any one has experience with it.

I used Roxul mineral wool to pack my mufflers. You also have to check the db killer's plug hasn't been removed or gutted. If it's wide open repacking won't do anything, the muffler will work like an open glasspack and sound like Cherry Bomb.
Pull the db-killer from the can and check to see the tube is closed where marked on the pic below. If it is open (and I'll bet you a roll of toilet paper roll it is) you have to fix that first. Either cap it or make replacement plug ( I think I used a 1" copper pipe endcap to repair a MAC db killer). I like the replacement plug as you can move it along the length of the DB killer to tune the exhaust note to bark like a dog or purr like a cat.

Chasing an annoying mid-rpm exhaust rasp that has developed. Either I’m about to drop a valve, or my Termis need a repack (after 13 years and 36k ). I guess i’ll find out soon.
i have a ton of Roxul/Rockwool sitting around but I am dubious. Is FMF still the best choice? Do I bother replacing the inner steel wool layer?
Gonna second this, from first hand experience. It works great at idle, you'll even feel proud of yourself! Couple of weeks later and 1/3 of it was gone. I also tried a whole bunch of rolled up fiberglass HVAC filters, glue and paper removed, packed as tightly as I could. I'm getting itchy just thinking about it. That also compressed and blew out over time, 1/2 gone after a few rides.
Bought a couple of packs of BikeMaster muffler packing, still need to get around to installing it.
repacked with FMF and it works well. Got ride of the higher pitch raspy sound that was developing.
Old packing didn’t look too bad, wasn’t burned out or anything but did feel very packed in. Also the inner stainless steel mesh sleeve was carboned up somewhat. So cleaned that up as well.
It is NOT a job i would care to repeat. What a chore. Hopefully it lasts another 35k
