The exhaust flange on my V8 just behind the cat is broken. The good news is that it is just a floating flange, not actually part of the pipe, so the pipe appears to actually be fine. I'd prefer to just replace the flange if possible, but it seems my options are limited. Either a split flange or a flange repair kit, neither of which is flared like I assume the original might have been. I also found this adapter from walker, which would just have me cutting off the end of the old pipe. The question here is, which I've found mixed posts in my searching, what exact size is the OE exhaust? I'd like to know this for certain before cutting the pipe off as I need to order the adapter. Thoughts or opinions on any of this? I've only got 92k miles on my X and the rest of the exhaust seems solid enough so I'm trying to avoid paying for a full catback just yet.
