Catalytic converters going bad - Muffled reduced sound + CEL COME AND GO

I think The MustangShow has the stock h-pipe from his GT500 for sale. I know the pipe won't fit, but could always salvage the factory cats.

Guy has a used stock pipe dirt cheap, long ways away but priced very right.

Hey Rick, I had one of my Truck drivers picked them up. Thank you so much for your findings for me!
:P 95 bucks for H pipe + stock mufflers + free delivery I think I just saved an upwards of or 500-600 bucks? loll

Hell I can probably resell the muffler for 50-60 bucks and gain some lost for labour.

Question for you all, Should I have A shop, chop and weld in an X pipe? Or just leave it as is?

I plan on cutting the H and putting this perhaps would it be cheaper for a shop to use make it?

More cost effective to buy a new X with cats.

Missed part of your message, leave as is and be happy happy happy.
Great deal you got there.

Would GT500 cats work on a SN95 if they could be cut and welded in?
Anyone?

They seem to have O2 sensor bungs in them, and no air tube. Could the air tubes be plumbed into the O2 bungs?

Bitch of a job to even attempt as the cats sit virtually right at the manifolds. To me, something you'd attempt yourself, doesn't make sense when your paying labour.
