Factory Exhaust Flange

[Matthew Jeschke]

I think I may have brought this up in a different thread. I pulled exhaust off a suburban, cut the intermediate pipe (collector to muffler) shorter and welded it together so it would fit my Tahoe. Any welds I do, any clamps I try, just break when I go offroad.
My plan is to install a second flange in front of the muffler so I can (1) better weld the exhaust and (2) pull that intermediate pipe out. There's no way to pull the muffler off without pulling the whole rear end off or cutting and welding sections.

Long story short, I've been shopping flanges and really really just want a 2nd factory style flange as image below. I have the other side (in my junkyard scrap pile) but don't have the collector side...

Any idea where to just buy that flange?

This is the part that keeps breaking. I had to cut it where the green arrow is and take some length out of it... I've now welded the piece a half dozen times and put a collar on etc. etc. etc.

I bought a better welder this last time... Long story short though, would be MUCH simpler to fix and work on this stuff if there was a flange at that green arrow.

Is this something that a local custom exhaust shop do for you? Or, potentially just supply you with a flange?

Not sure I suppose I could call. I don't often use shops.

Only other place is the junkyard but they typically cut the exhaust after the collector when they pull the motor so the flange gets thrown away. I was just lucky enough to score a truck that hadn't been processed yet years ago when I got the last exhaust.

Otherwise the flanges available all seem to be one size fits all and I don't trust they'd work as well. That factory one is pretty robust and creates a strong connection.
