not unless you have headers hanging off your tailpipe
if you look at a view of an exhaust system, you have the manifold (or header), the catalytic converter, and the muffler. the components go in that order from the front of the truck to the back. so cat-back means your swapping out the system from after the catalytic converter and back. if you just change the muffler, but keep the stock piping....that isnt a cat-back system. its just a muffler swap.
a high flow cat would be a waste unless you are running a S/C or turbo or have a heavily modded engine. a stock replacement would be more than adequate. besides, you will probly have too much flow if you run the high flow cat with headers and you would loose power
