Help - I need a catalytic converter for my 80 series!

[BamaLC]

So I let my local mechanic convince me that my cat was giving me problems in 2020. We replaced it with an aftermarket from full line exhaust. Now needs replacing (of course) but I'm beyond the warranty of 25,000 miles. Should I get a factory, even if used, and if so where? Any advice would be much appreciated.

What year is your truck?

Why do you think it needs replacing again?

Sorry, its a 1997. Mechanic says rattling is coming from inside Cat 1 coming from engine.

Get a Magnaflow unit. Very easy to install unless they butchered it.

A number of us have installed these and are on 4-6 years with no issues.

I am going to be using Magnaflow when I do mine, either the universal ones or bolt in.

Do you do any of your own work?

I have done a fair amount of exhaust work in my life and the exhaust on this truck is the easiest I have EVER done, and I live in the Midwest with rust.

You can look up the parts list here in the following thread:

Bosal , your $200 cat-back option

I wanted to put this here for anybody thinking of re-doing there exhaust. When I started this project my exhaust was bad, really bad. It was leaking at the seal between the rear cat and the cat-back. Only one of the exhaust hangers had not rusted off and it was being held by some pipe strap...

Did the Magnaflow + Magnaflow second cat recently and it these pieces bolted up great. Rest of the exhaust was Borla and I needed to finesse it a bit to mate up with the Magnaflow but I think that was due to the positioning of the hangers on the Borla. Overall not too bad installation.
