I just found that I have an exhaust leak in my truck right at the **** on the back of the catalytic converter. The **** looks to rusty to try to take off the bolts and replace the gasket. I only need to get this truck through the next few months before we are getting rid of it. I know that they make a muffler patch but the heat is alot lower at the muffler than the cat. Any ideas on a patch or make shift fix to get by for the next few months? Dont need pretty just functional.

Thanks
Dustin

    take it to a muffler shop, have them replace the gasket and just weld it completely shut. or, just have them weld it completely shut without replacing the gasket. Not a big deal it sounds like.

    Permatex makes a gasket maker that goes to 700 degrees. It's their Ultra Copper Gasket Maker. It should do the trick. Just use a wire brush to knock the rust off from around it so that it makes a good adhesion.

    Found the actual description for it. The Ultra Series - Permatex® Ultra Copper® Gasket Maker The Ultra Series - Permatex® Ultra Copper® Gasket Maker Premium silicone that can withstand operating environments to 700°F (371°C) intermittent. Fills gaps to .25" when fully cured. Superior adhesion. Three times more oil resistant than conventional silicones - eight times more flexible than cut gaskets. Suggested applications: Pumps, compressors, exhaust manifolds/headers, valve covers, oil pans, thermostat housings, gear boxes.

    Go to a shop and have it welded and be done with it, pic if possible will also help!

    I am trying to get in touch with a friend of mine who has a welder that I can use. Any tips on how to do it? I have done some small stuff with a small mig but nothing like this. Should I just clean up the **** as much as possible and weld it shut?
