what's next?

after quite some time, i'm finally starting to get back into buying stuff for my car (99 non-vtec accord). right now i've got the basic upgrades... aem CAI, thermal catback, dc sports header, neuspeed strut bars, etc... i've got a few questions for the pros before i make any more purchases...

turbo is out of the question for now, but i've been considering a hi-flow cat, fuel injectors, a/f controller, ignition setup, and things along those lines. what's worth the $$ and what's not? i'm just getting extremely bored with my car and need a little something to bring it back to life.
