Kind of a stupid write up in some peoples eyes, but to others, gives them an idea
I bead blasted my can while I had it out so I could paint it when I was done.
1. Drill out all the rivits
2. Order muffler fiberglass (got mine on ebay for like 8$ shipped, its ment for motorcycles)
3. Cut into 3 equal sheets (or 2 for you twin boys)
4. Wrap them around the expandable metal and insert
5. Insert rivits (mine were aluminum bought that quality farm and fleet)
Presto.. you got a new can again. I have heard every 3,000 miles the fiberglass wears out and it needs changed. I don't know if that is true or not but for 8 bucks and drilling out some cheap rivits, what the heck.
I think the new cans use steel wool so they don't wear out (black magic does I think)
