i repacked silencer today and i would estimate 5db lower than it usually is after being freshly packed.today when i was on my way to go buy packing i decided to try something a little different.i remembered one of mechanics from peninsula kawasaki used to pack my silencer with steel wool he said "it was his secret weapon".at the time i was only about 14 so that was good enough answer for me.so instead of going to cyclegear for packing i went to home depot and bought steelwool x00 the finest stuff they had.i then packed silencer same as i would with normal packing.when i fired bike up i couldnt believe how much quieter bike was.it also sounds different more of a hollow thump like old school thumper.bike runs same no power loss.the only thing is exhaust smells funny and smokes after i shut bike off like steelwool is smoldering.im just wondering how long steelwool will last compared to fiberglass packing.

Yznvegas: Well, based on the whole smoldering part, I don't think it is going to last all that long. :)

Stadard steel wool won't last long at all. You need stainless steel wool.

Yep, mine had SS wool in it stock. When I repacked it and replaced the SS wool, I used SS scouring pads (without the soap of course!) from wal-mart, and then wrapped that with external exhaust wrap, and wired it as tight as I could. Sounds stock and lasts a long time.

That stuff burns.
If you don't believe me touch a piece of it to a 9 volt battery and see what happens.
You need the stainless steel wool.

get a 400exc silencer and put it on your yamaha,then youll have the same power and a much much quieter bike. I know a few people that have done this,it really isnt that much work.
