Gutting Cats
I am getting my gmmg exhaust soon and while I'm installing it, I want to gut my cats. What do I do to gut them. Also Is there anything I need to buy so I wont throw any codes? Would I need rear o2 sims? TIA.

Re: Gutting Cats
It is a simple procedure,unbolt your cats,hammer away at the inside honeycomb material with a long prybar/screwdriver etc. Have a trash can nearby because the catalyst material will break up and pour out. (Might even want to wear a mask because of the dust it will create. Bolt them back in and procede with the catback install. You don't have to install sims if you don't mind the SES light being on(it will throw the cataltic converter inefficient Bank 1&2 code)But if another problem develops you wont know with the light being on. So get the sims or tuning to eliminate.

Re: Gutting Cats
And if anyone is interested I did a ASM dyno test on my 02 SS after gutting the cats and with the Hotcam and it passed the standards set for a 95 LT1.(Last standards available since 96 up are OBD tested)

Re: Gutting Cats
Thanks for the replies. Does anyone know if these codes will hurt performance in any way? I would like to get the sims but they are expensive and I don't want to get them unless I need them.
