Cut exhaust crossover or deal with it?

I need advice from people smarter than me...

I'm in the process of replacing throwout bearing, clutch, PP, etc. and in a how-to the poster wondered after the fact about cutting the exhaust crossover section under the transmission, then re-attaching with a couple of exhaust clamps. This got me curious but I can't find anyone else who's tried this.

That makes me think it's not the best idea. If it was, there would be more stuff about it.

Here's what I'm thinking:

PROS
Accessing/removing the trans would be much easier
Not having to remove the exhaust would be much easier
Changing trans fluid would be somewhat easier (I made a tool for this, so that's hot a huge PRO)
It's below all O2 sensors so I doubt they would be affected.

CONS
Increased chance of exhaust leak
Two cuts could add flex (Would pass. side need a hangar?)

I'm sure I'm missing some pros and cons, or I may be way off in my thinking, so feel free to add your thoughts. All thoughts and help is very appreciated!

If anyone needs to know vehicle stuff:

Manual trans (or I wouldn't be doing this)
2-door

I thought that was in my profile to the left but I'm not seeing it. First post noob issues.

I did it. Only one cut. Joined it with a coupler and clamps. No problem, and made dropping the transmission much, much easier.

Thanks for the info. Where was your one cut?

Driver's side just past the transmission drop point.

With that cut location, removing the passenger side seems to be the harder of the two sides. But easier than both together I'm sure.

The nuts are captured on the top side of the manifold. A long extension or two makes the passenger side relatively easy to remove.
