Default gut cat
Is it safe to gut the cat?? I dont really have the tools or time to saw of the cat and weld a new pipe on so i was just wondering if I could just scrape all the honeycombs out??

are there and cons to doing so?

an ses light is not a problem get o2 sims or get someone to delete the code. passing emissions is not a problem unless you live in cali. look up your states laws on emissions first. and gutting them will make your car sound a lot better. its easy to do just get a long screw driver and a hammer

I say just take it to a friendly exhaust shop and have them replace the cats with straight pipe.

An SES light is a problem in some states, mine in particular. You will fail emmission with an SES light, no if's, and's, or buts. Sorry pal, Cali. is not the only emissions strict state. Just to delete the code with custom tuning, several hundred bucks there. Wait for other mods if you plan to delete them. And IMHO, it will make your car sound like ***.

Seems like now would be a perfect time to upgrade to some LT's and catted y.

Do LT1's have dual cats? I wonder what would happen if you gutted just one and not the other?
