Tom, I forgot that you have not yet seen the horrors birthed just down the street from your pristine mopeds.
I used steel wool to pack the silencer I welded on to the pipe in the attached picture.
Said pipe was once furniture. Said silencer was once a Tetley's can.
Anyway, I use steel wool or copper wool depending on the material the exhaust pipe is made out of. I've got a bunch of copper wool scrubbers left over that wouldn't oxidize inside an expensive performance pipe.
Give it a try? Not even close?
