First headers don't increase power.
They are designed to move power band lower or higher, so you need to know what you traded for, and then decide if thats where you want the power band shifted to.
Stock exhaust is tuned for mid-range power band.
From what I read Florida no longer has emissions testing so removing the EGR system probably wouldn't be illegal but don't know for sure.
If you do remove it you will get a CEL(check engine light) on all the time.
And because the EGR system helps reduce "pinging" under load, you may have to run higher octane fuel all the time.
As odd as it sounds, exhaust gas "cools" the cylinders when engine is under load, this prevents cylinder from getting too hot and preigniting fuel during compression stroke, pinging.
There is no power increase from just removing the EGR system.
So I would have the headers modified for EGR pipe if you decide to use them, it will save you money in the long run.
