Default Gutting Cats

Is it possable to gut the cats on an 02 Z by just seperating them from the y pipe? Also what are the odds of the gaskets being good when I take them off? Any suggestions, Help,ECT?

Gutting the cats shows no improvement. What you gain with out the honey comb you lose in velocity with turbulance. Not to mention the horrible sound it makes because its a empty coffee can now.

If they are setup like an '00, then no. Maybe the drivers' side but the pass side would be tough w/o taking loose from the manifold. And for all that work I would rather install a set of headers.

see if you can get a custom better y-pipe, i would sell you mine, but i'm chopping it up and fitting it to my headers, its that good. But it moves the cats under the car, and the sound is better, i'm really just using the heat shields and merge from it, but the rest would probably be worthless to you afterwards.
