Gutting any cats will make your car sound horrible, and you will notice little to no gains, pollution of the air increases, and you will have to deal with the smell which will give your girlfriend headaches!
If you are looking for a cheap solution look at the borla headers. They give a great sound, and a small boost in power. Certainly more than you will see from toying with the stock headers. At 220 they are not THAT expensive.

Do you have anything else in the intake/exhaust system modified?
Ahh... I see.

I know what the impact would be if I gutted all the cats... just curious what would happen if I gutted one, as I didn't think aftermarket headers even had cats (typically, I know you can buy them w/ cats)

As to the Borlas, I'm not going to bother w/ those. They are not going to give me any gains at all... and lord knows how long they'll last.

The other I/E mods I have are: 3" intake w/ K&N panel filter, WRX axleback.
