Gutting cats
Gutting cats How much work is involved in gutting out the cats on a 99 Z28, Do I have to take down the whole stock exhaust, or does the cats un-bolt from the exhaust and worked on ? I'm trying to find a diagram of a exhaust system for the f-body. Thanks for any help
Its not that hard to gut a cat. All you have to have is a pry bar to reach in there and break the packing up. But if you just gut your cat your going to cause turbulance in that area of your exhaust. To properly do this you need to run a straight pipe through the cat. That was it doesn't create unwanted turbulance and from the outside everything looks stock.

I'm in BFE Texas 
theres no need to weld anything, you can take them off and completely gut them with a rod....there will be more noise and more smell.....jeclair i see your in jacksonville, if you need some help let me know
Dont gut your guts unless you run a straight pipe thru them. without a pipe they act as resonators so know you've added 2 resonators to your exhaust and made your flow worse + the smell.
