does this happen when engine is cold? and how long have you notice this happening? With the long tube headers your O2 might not be getting to operating tempture, causing you to have a lean condition.

well the SES light that came on about the lean condition was when i was driving down the highway.. the car had definately gotten to operating temp a long time before it happened. I noticed my car had been driving kinda slow for a while. first i beat my friend with the intake and exhaust, then i just barely edged him out by .1 a few months later, and last night i lost to him

That seems kinda high. Sounds like LS1 fuel pressure.

so here is my checklist of things to buy tomorrow:

Seafoam for the gas tank
Throttle body cleaner
MAF cleaner
and im currently working on getting a new y-pipe since mine is ****ty and has all sorts of leaks all over (this is after the o2s tho)
I will update and hopefully people on here can help out with other ideas thanks a ton everyone

ill try to get a gauge to check the fuel pressure as well
