OK cracked a flange at this center joint and had a muffler guy do a quick weld to hold things together temporarily- I have some spare exhaust parts and I want to put this all back together relatively stock-ish. I looked on realoem and I just can't quite make out what happens.. looks like the non-flared pipe coming off the cat gets a cast flange and a seal ring and that's it? And then the other flared section has a smaller seal ring sandwiched between it and the flared pipe from the muffler? If anyone has a photo or can explain that would help me out a lot.
