should I?

[scupking]

I’m getting the urge to get some mac flowpaths welded in. Would there be a sound/performance differences between the Mac catback and the weld inns? I don't think there would be a difference but that is just my guess.

I noticed a difference with my Flowmaster Catback after I replace my Flowmaster weld in mufflers.
It seemed a bit deeper due to the larger pipe.

Yeah, I think there would be a slight difference because the catback system has a larger diamter pipe. You'd still get a nice note by just welding in mufflers though.
