Basically I'm wondering if the next restriction to replace after the header & over-pipe is the second cat or the OEM muffler?

Correct me if im wrong (someone else) but replacing the OEM catback would probably liven it up way more than making your front pipe catless.
Edit: actually im 100% sure replacing OEM catback would make liven it up more...
