The standard muffler wasn't stainless or anything fancy so welding it is easy enough - the rust holes at the end of mine get welded up every couple of years or so.

Who done your welding for you, I have been to 3 muffler places and they say they can't do it, I suspect they want me to spend $200 on a replacement.

ps: I live approx 3/4hr from your area.

I wouldn't bother, although a master welder using TIG or oxy acetylene could easily weld it, the metal is very thin and prone to fatigue cracking. A piece of sheet metal, pop rivets/self tappers and high temperature silicone sealant would be a far better solution for patching the bottom of an old muffler. Let it all cure for 24 hours before driving a siliconed repair.

I do my own with a little MIG welder.

If it's a straight weld job, I can have a go at fixing it for you.
I don't have any scrap sheet metal around to make a patch though.

Thanks for the offer, I have had another go at repairing it via the piece of sheet metal, pop rivets and high temperature silicone sealant as suggested by "bee utey" and others, so will see if it lasts longer than 3days this time.

Here is my latest attempt (3rd time lucky I hope) to fix the muffler - (see pic).

Found a bit of roofing tin under the house and used Maniseal exhaust cement as a sealant and heaps of pop rivets of various sizes to give it extra strength.

May have to put some more rivets down the bottom but will see how it holds up first

I can't see why that won't work, it'll probably outlast the muffler .
