I did a search on "+Specialty +Spares +washer" (without the quotes) in all forums and got 13 results. I don't have time to go through them but you might try it.

Well I added some packing to fill in that part of my SS baffles that wasn't wrapped. Went for a short ride (5 hours) just to see and... marginally quieter, I think, maybe. Anyway, still not enough to make the pipes user friendly. Next, I'll reverse the baffles so the louvers on the perforations face the outgoing exhaust (Richard's idea).
Still got a serious raspy high pitch sound that's got to go before I can enjoy the pipes. Also, I think I'll slide the baffles right out to the end of the pipe. The tips will keep 'em held in there and I'm thinking the longer the empty chamber between the clamp connection and the baffle, the deeper the sound (kinda like a trombone).
I'm working on it. 
The void you see here is now filled in with packing.

Some sort of fiberglass stuff from an insert made for some other bike. I know that doesn't answer your question very well but a friend at a Yamaha dealership just handed me this thing made up of wire mesh and fiberglass and I peeled off enough layers of glass to fill in the void on my baffles. I then wrapped it with heat tape to hold everything in place.

Keith, did you put in as much as the diameter could handle?
Just had a look at mine and the direction of the "scoops" goes rearward on mine.
They are loud, but mine have a nice tone, not what I would call raspy. One thing I have noticed, "loud" is a very subjective term to the beholder. Dean down in Arizona (who got busted for loud pipes) would not think Specialty Spares are loud. My wife thinks mine are too loud because she can hear me three miles away. I had a trike that could be heard 5 miles away...and I didn't think that was too loud!
I wear ear plugs for wind noise alone is too hard on your hearing.

Yup Eddy... I wrapped those things as tight as I could get it. The raspy sound has been reduced by a small percentage but it is still there. The 'scoops' or 'louvers' faced rearward on mine too, that is until today. Richard had an idea that turning them into the flow of gas might help make them quieter. I did that, but with little to no noticeable difference. I will try a couple more things like the washer idea and if that doesn't tone them down I'll consider letting them go.

Keith, measure the diameter of the hole in the baffle and post it please. Ill install my pipes in a few days and measure the old baffles as well.
I wonder if Dale used a different baffle.

Okay... I'll get that measurement tomorrow (the I.D. of the perforated pipe, right?).

Sorry, Z... I never got around to doing this today. Life happened, and for the next foreseeable future I can't see pulling those pipes for a measurement. Soon (because I want to resolve this issue)!
