Can I get some help with a supplier for the part circled in red? Thanks

 

Generally it's a part of the cat, for direct fit applications anyway. On the OE cat it's not a separate flange, it's welded to the case. You could hit the Walker Exhaust website and browse thru their catalogs, but I doubt you're going to find the flange alone - they'll want you to buy the entire cat.

On the flip side, it's usually just a 1/4-3/8" thick piece of mild steel with a big hole and 4 drilled/tapped holes. You could hack one out with a hacksaw, use a hole saw for the large hole, then just drill/tap the rest.

 

Thanks, I checked out Walkers website For a few minutes on my break today, if they sell individual parts they don’t make it easy to navigate to those pages, I’ll look again when I’ve got more time.
I'm in the planning stages of making my own y pipe and “off road” pipe to replace the janky y pipe and Cat that came with the used shorty headers I put in the car years ago. The Cat is a universal piece that doesn’t have the flange I’m looking for. I have access to all the material I would need and a water jet so making one is certainly an option. If this was a readily available part it would be worth my time to spend a few doors on instead of designing fabricating one.

 

The impression I get, is that they don't sell them specifically to prevent people from doing what you're trying to do (eliminate the cat). Walker has PDFs for hangers, flanges, gaskets, clamps, etc. There's no real easy answer, just go thru each of them and see what's available. Chances are the closest to something that will work is a 2-bolt ball flange.

 

The thing you circled is in fact part of the cat. Not a separate piece.

For inspiration, look at the piece that it bolts to, that hangs off of the transmission tailpiece. (which I think you CAN buy new) I think you'll agree, it would be VERY eeeeezzzzzy to fab up something to take its place. In fact I've done that myself in a couple of situations. Seems like I used a 4th gen version of the transmission piece on my T-56, and made up something real simple like a L-shaped piece of strip stock, to go on the pipe.

I REALLY like the ball flanges BTW. They are by far the easiest thing to put a system together with that's maintenance-free (unlike the stainless band clamps that the pot-metal piece rots out of for example),easy to take back apart, and virtually leak-free.

 

I found someone on Facebook that sells Thirdgen parts, a cat with the pipe cut off, $20 shipped. Not bad I suppose but I decided to just fabricate my own.

 

We’ll see how this works.

 

At one time you could get "repair flanges" for that location. It was a 2-piece deal where the two halves bolted together, but it was just the flange and nothing more. They were meant to fit the original converter case.
