My catalytic converter is "falling apart", need opinions on what to do Options

[SnowMan]

alrite, not too long ago i picked up an eastern high flow cat,
a resonator, and a muffler. i had meineke bend me some
2.5" pipes and it was great. 2 days ago, i realized that as
soon as i go over 2k rpm's, theres a really nasty rattling
sound. after bringing it back to meineke, i was told my cat
was starting to fall apart inside and that it will only get worse.
obviously i need to change it, but should i get another high
flow, and also would it be worth having them also change
my muffler while doing the work so i can upgrade to magnaflow?

Got mine off Ebay for 50$
I go catless though. Maybe we can see some flamethrower!

I'm catless, and I don't have flames that I'm aware off. If I put a spark plug in my muffler and hooked a coil up to it, I might get some action. Got to run rich too, which means bigger injectors.
