My exhaust rusted out right before the muffler, and then entire pipe is broke off. It's a 2001 blazer. Does anyone have any tips on how to repair this? I have a welder, but I don't know if that will do well on a rusted exhaust. Is there any clamp on parts I can get to fix?

It broke off very close to the flange. So I may need to take off the bolts and get a new one. Any tips or help is much appreciated.

 

where that break is its just too thin to weld. my fix would be to cut like a inch of pipe off from the left of that picture, then just cut the flange off and throw it in the garbage. clean the metal with a wire wheel as best you can and find a piece of pipe thats going to barely slide over it or inside of the two and weld it together.

you can butt-weld a piece of pipe in there but thats a little harder to do

also the hardest part of welding exhaust is trying to get to the very top.

if you can find a really tight fitting pipe you can probably get away without welding period, maybe put some muffler cement in there and clamp it down

 

exhaust shops will fix that for dirt cheap
Just tell them you want that spot patched.
