Replace the cat. That's probably about 1/3 of the extra noise right there. No, the cat's not going to make it higher... lower if anything, but less... well, ricer Honda Civic farty.
If you want good power from a SLIGHTLY better than factory setup you could go with something similar to my last one: High flow cat, 2.5" piping with as few bends as possible, AeroTurbine 2.5" resonator, Borla Pro XS muffler (single outlet). If you want to knock it down a little bit more go with the dual tip version of the muffler OR go with the single outlet and add a "Y" pipe with the tips on there as the outlet. The Y pulls the volume down further.
