Rusty OEM Section 3

[AWE46M3]

Hey Group - anyone have a solution for the crusty / rusty section 2 to section 3 connection on the section 3 side?

My flanges are rusted and the OEM square nuts are frozen to the hardware. There is a broke bolt on one side. I’d love to cut these off and replace the flanges with something better.

Anyone refresh their section 3 and find a good solution for this crusty connection?

Thanks in advance

I was going to use these in your situation but my flanges were okay.

Thank you - this looks promising. 🤝

One of the flanges cracked on my muffler. I bought a set of the X8R split flanges. Unfortunately, they're just a hair too small (ID). I had to bore them out a little. But now it's working well.

But they fit so well in the YouTube video 🤣 Of course the ID is too small. I need to have the current flanges cut off so I’ll have the muffler shop shave the ID down for better fitment. Thanks for calling that out
