Any exhaust shop can do this, however it is illegal to remove your cat from the exhaust system. 10k fine to the shop, and 1k fine to you (I believe).

I hear a place called Rainbow? or something in St. Pete will do this, Although don't quote me.

I have friends that can do this for you. Just bring the pipe, and some cash. I don't know how much they'd charge. Have Keith get in touch with me.
