Default Replacement Catalytic Converters

I have a 98 Z28 with headers and Texas speed Y with cats. There is a rattling noise that I can't track down and believe a cat has broken apart inside. Anyone know of a replacement cat that will work and fit? Thanks!

I bought a replacement magnaflow converter for my 1998 v6 firebird last year from advance auto. It was a perfect fit and I've had no problems with it.

I'm tempted to just remove both cats since there isn't any inspections where I live. I put them on to basically tame the SLP Loudmouth 2 catback. Thanks!

If you have a crowbar and a "disposable" long drill bit,
removing the brick or its remaining chunks is an easy
(other than dealing with the rusty studs) chore. Just
drill enough into the zirconia to make some stress
concentrating holes and commence to ramming.

The bricks in my Chevy van were even easier; a
demolition hammer tore them apart like nothing (but
I had to cut trap doors in the housing, because the
cats are welded in 6' of pipe from the factory).

You'll find it a little bit "boomy" in the midrange but
free might make you tolerate it.

I now run with Mufflex tubes which are bolt-in plain
pipe. Not sure they sell them anymore, and when they
did they cost about as much as new cats.

There's also some outfit like "Cold Fire" or something
similar, that sells fake / hollow-shell "cats".
