Gutting the Cats How difficult is it to do? I have LS1 edit so I think I can make all the codes behave. The car will be up on lifts Monday while a friend puts in 3.73 gears. I was wondering if we could gut the cats while it is up. Anyone done this yet? What are the pros & cons?
Thank-you, Becky

Re: Gutting the Cats Pros are better sound and flow for sure. Cons would have to be that you don't get the raspiness and flow of a totally off road y pipe. You may not like the rasp, but its a con to me if you don't get it.
Re: Gutting the Cats You'd want to take the cats off the car.
I've only gutted one cat, on an older
vehicle. Basically, you have to make
the ceramic honeycomb shatter into pieces
cmall enough to come out the hole. I used
a crowbar to ram it; a zip gun (air chisel)
might be better. One of the cats looks
easy, the other has more length and bend
to it and would be a little more work.
It took me maybe 15 minutes of determined
ramming to get her off <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> Once it goes, it
goes fast but the alumina substrate is tough
stuff. A more pointy tool (like the air chisel)
would make easier going.
I don't know whether you need O2 sims for
a gutted cat, or not. I guess not, with Edit.

Re: Gutting the Cats Becky,
You'll be miles ahead if you go with high-flow cats from one of this board's sponsors'. Don't gut your cats if you have to pass a emissions check. If no E check, run Hooker long tubes and the cat-back or duel exhaust of your choice.
Enjoy your cars.

Re: Gutting the Cats Listen to NC Guy.
If you really feel you must gut cats, try an nice Randall Model 21 "Little Game" @ $225. It would probably fit your hand well.
