    Need the OEM gaskets for the upstream cat that connects to the engine manifold and need the gasket that connects from the upstream to downstream cat. Any ideas??

    thanks

    I got mines from oreillys. What they showed in the system for my truck didn't work so I took my worn ones and match them. I used high heat silicon when putting them on and the CEL went away once all plugged in

    Pretty hard to know just what you need since you don`t mention what you have

    Sorry. I was trying to replace the upstream oxygen sensor but the nuts were absolutely shredded. So I removed the upper Cat. Now I’m torn between replacing the upper cat and reusing the old one. The OEM upper cat is $1200. Any good aftermarket one that are reasonably priced?

    Not sure where you are...my local guy (northern Cali) welded on some aftermarket cats and seem to be working well for the past 2 years. He is Dublin, California and I can get you his info if you are local. PM me

    Year ?? Engine ?? they can be a little different

    Since you don`t say are you dealing with New York or California CARB compliment exhausts

    Not having to I use Walker Cats with no issues

    Cut the old bung off install a new one if you had no problems with the Cat

    And I would not really replace the CAT if it is at all salvageable...why spend so much money for something that was working

    I have one of those in stock but from a 2.7. See if you can grab used one, probably around 100 or so
