resonator or catalytic. Options

whats a good deep tone deep hum resonator out there? like a greddy sp2? I have ebay headers and a 5zigen full 2.5" exhaust with bottle type resonator (looks like an SP2). What will help it get deep? Right now, its not so loud but it is high pitched on the higher rpms after i had put on the headers.

Options:
1. remove catalytic make straight pipe (may get louder)
2. remove catalytic make straight pipe and add vibrant ultra quiet resonator
3. add high flow cat and vibrant ultraquiet resonator
4. just add high flow cat and keep what I already have the bottle style resonator

I don't have any emissions laws so you dont have to worry bout telling me its against the law or its illegal. just trying to cut my time and money short rather than experimenting myself if any of you guys have already gone through this trial.
