I have a 79 (I know, I know, I know... technically the wrong boards, but i used to own a 73 500 and i've grown to like it here) with a stock exhaust. The right lower muffler has a decent sized hole in it on the bottom near the header. Other than that hole though the exhaust isn't perfect but is in pretty good shape and still looks nice.
I'm having a hard time finding a replacement, and I'd really like to keep the stock 4-4s. I stopped by a muffler shop yesterday to try to see if they'd weld a patch over it, but the guy told me the material was too thin and he'd just end up burning through it. He also said that even if it was welded it would rust through again fairly quickly.
I'm wondering what you guys might have done with a problem like this, or if you have any other recommendations. I tried a wrap that is supposed to seal itself with the heat from the exhaust, but I couldn't get it to seal real well and it just fell off after a few minutes. Unfortunately it's not exactly running the best with the hole and ran amazingly better while the wrap was on.
