Depends on your mufflers.
The engine needs a bit of backpressure in the exhaust for low-end torque.
If you're running stock mufflers (a bit restrictive) then I'd say punching out the cat could gain you a couple of horsepower.
I don't know what the emissions are like in Florida.
Do they test? How often?
If they do test for emissions, I'd recomend a high-flow cat from Rantom Tech.

Florida has NO emission testing, great thing huh? any way, getting the hammer and chisel out.. took the exhast down today and the cats are a biotch to get at.. so im gonna drill them out and vacum them with a shop vac, after i use a chisel on them.. inside of course.. thanks for the reply.
Where is Florida are you?
Anyways, I highly reccomend against gutting the cats. That can do more harm then good due to the way the exhaust gases will flow through it. Go to a muffler shop and have them make you a piece of pipe to completely replace it.
