How To: Gut a cat
Leave Morris alone!
I've done a search, read, and have a few questions:
1. does filling the cat w/ acetone work?
2. do you just simply take a long screwdriver & hammer to beat out the insides?
3. Are there any other ways?
I'm asking caus I have an '86 N/A w/ 186k miles and I'm not sure if I want to put a bunch of $$ in it just to have it die in 20-30k miles.

I wouldn't gut the main cat unless you have to. It sounds of *** and usually leaks. Plus you lose alot of velocity. Just gut the precats.
I use a big prybar and a hammer to gut them.

No cash right now to have a straight pipe put in, but if it sounds that bad, I will in a month or so, when I don't have to pay for preschool...
ya, it would have to be just the precats for 5&6 ports

I had gutted cats before. My word of advice is dont do it unless you are really really poor that you cant even afford a damn pipe, or if your pre cat is clogged. The performance between a set of gutted cats and a high flow RP is very close. Its not worth the time and effort.

First, you get a sharp knife....
oops, wrong kind of cat
Seriously though, I had a 1/4" steel rod that was a few feet long, and that worked great. Pretty much anything solid you can get in there and break it up with will work. And then jusy bash the hell out of it until its all broken up.

Yeah, be careful though, I did this today and the **** that comes out is very poisonous. Evil ****, I was thinking of just getting a RP and N1 Singles, good idea or not. I have gotten a lot of varried answers so I want more.

Yes, there is more than one way to skin, err.... I mean gut a cat. I did mine because I was only boosting about 3#. A long slender screwdriver and some time was all it took. Most of it came out in large, fractured chunks. They were melted down something awful. This was just a cheap fix. It does leak and does sound, umm, "different". I have a 3" frontpipe that's waiting for an appropriate catback.

Don't gut your cats. Sell them to autocrossers. I just read an article on how much it sucks to autox an RX-7 in stock or street prepared because you MUST use the FACTORY converters... the factory stuff is like $2500, or more than most RX-7s are worth.
You can't buy them from junkyards, either - it's illegal.
