Running without a CAT?

[danthemanx07]

Here's the problem:
My Check engine light has been going on and off over the past few months because of my oxygen sensors, so I imagine that my cat is pretty well clogged with crap, also, along the tailpipe, where the cat is welded up, the weld is absolute crap and there are holes all around the pipe, so i probably need a new cat and o2 sensor

my solution:
i was thinking i would cut the cat out, and replace it with straight pipe and keep the muffler, get an o2 simulator and be done with it

i know that this is illegal and carries a big fine and all, but here in MS we dont have emmissions checks, so i am really not worried about it, has anyone ever done this? any experience with o2 simulators?

my biggest concern:
how loud is my 318 v8 going to be without a cat?? i dont want to get in trouble because it is too loud and i do enjoy the use of my hearing

DO IT!
simulator will be about 70 or 80 bucks
factory sensor will run about $87
I don't have a cat and it sounds about the same...

awesome thansk for the help, i have been wanting to do this for a while, but have been hesitant becasue i dont want it to be too loud, i will probably have to wait till i get up there, which is only next week though, i have a lot of stuff to do before i leave here on tuesday, anyone want to help? i guess i will need to get some pipe to replace the cat, more work for fab night!

did you ever get any pipe to replace the cat? I still have that piece that came off of mine if you want it before I scrap it.

yeah i went to a shop over the break and got the to weld a piece in there for me... it certainly doesnt sound as mean, but it will work for now
