catalytic converter

Hello. My excursion doesn't have a cat previous owner removed it. I believe it might have the stock muffler on it though. Just wanted to know if there are any cheap aftermarket universal ones that would work fine. Other than the walker direct fit.

Cheap ones often don't work. Buy a brand name, used OEM or (choke gasp) new OEM.

Hmm yeah so would you say walker is good? And I wonder what he did with the o2 sensors because I believe the only code it puts out is a misfire.

Unless it's a Cali spec build it doesn't have an after cat O2 sensor, so the two sensors before the cat don't know if the cat is there or not. That misfire code could be why it doesn't have a cat on it, if it's been missing for a while it could have fouled the cat with coke from the raw gas out of the dead cylinder. A long term miss is the best way to kill a cat........
