Im attempting to rebuild my greddy sp muffler which the straight through baffle had rusted on the welds and fell allowing all the packing to escape. What type of packing should i use and where can i get it from? also where can i get or make a baffle to replace the one that maybe too short now to connect the inlet and exit of the muffler can itself. will post pics once i get it cut open.

 

Fab section would be a better place for this.

 

I rebuilt an old cheap twin loop using motorcycle muffler repacking kits.

 

There are a few materials that you can use. I rebuilt my Tanabe exhaust with some Moose Motorycle exhaust packing, but I wish I had used more and I would have like to have used ceramic exhaust packing. If you look in the home made OE twinloop, there is a link to some excellent packing material.
