On an otherwise stock exhaust setup, I wouldn't think just deleting the secondary cats would make the car much louder, right?

For most people, this is exactly what they want: just a bit more sound.
So I recommend getting just the mufflers. No HP gain really, but sounds great!
Power gains via exhaust go as follows:
1) headers - largest power/torque gain, but with all else equal, will come with a little bit of rasp
2) section2 (x-pipe) - second largest power/torque gain, with slight sound increase
3) section1 (s-pipe) - third largest power/torque gain, with slight sound increase, and A LOT of rasp if you put in unresonated section1 and already have headers
4) mufflers only - least power/torque gain, with major sound difference; changes the car's tone quite a bit, without changing the characteristic of the motor (obviously)
You
could do JUST section1 or JUST section2, but they won't be as noticeable as changing JUST mufflers.
