Default Catalytic converter: replace or fix.....

Hey guys... The front flange on the cat has broken.... overall the exhaust seems fine down the line.... but does this look alright enough to weld the flange back together, or does it need replacing altogether ie. new cat..????

Delete it if your state/ city doesn't require emissions, I imagine it would be cheaper thwn replacing the cat

An exhaust or muffler shop might be able to weld it back together. Definitely cheaper than buying another cat if your municipality requires it for emissions. Otherwise a piece of pipe makes a pretty good replacement.

Rockauto has replacement cats for a good price.

ASFAIK... its required, but we dont have emissions testing anymore....

I can do the welding aspect of the repair...
Question being..Am I able to just clamp the flanges together and run a bead to hold it together..... Or does this require bolting/gaskets do to some flexing requirement in this area?....
Exhaust of this manner aren't my strong areas of note....

Ive seen a few on the Amazon.ca
this ones is cheap enough....

I ran fit for you using a 92 base with the 2.4L engine. Says it fits. Magnaflow is a good company. I don't agree with the description where it says 'increases horsepower and torque' though. Any back pressure decreases horsepower, but if you're asking, I would buy it and just weld it in place.

I've got a MagnaFlow Universal Cat welded in place on mine. Works fine.

How did the exhaust flange break? Did you run over something that knocked it loose?

We don't have emission testing at all down here but I still replaced mine, it was basically empty already with all the material sitting inside the muffler and pipe after the cat. I bought my direct fit cat from Rockauto and there was a rebate at the time so I only paid like $50 delivered. Plus I didn't want to smell gas all the time.





this is all that came out of mine:





and some was jammed in the pipe:

That is messed up! I've never seen an exhaust pipe clog up like that.
