Exactly! (again)
I had my muffler guy weld in flanges so I can change out between:
1) Straight pipe
2) Bullet cats
3) Humongo industrial cats

DD is #2 for smell reasons.
Mojave Mile/ Mojave Magnum #1
#3 to (try and) pass smog check.

I have a Kwik-Lift and have gotten pretty good at
changing them.
