maybe a gain of 20 rwhp, the more flow thru your motor the more power. I would do the Headers with out question. The coating is good for keeping the header heat inside the headers and out of your engine bay. Horsepower is all about how much do you want to spend. Do it you will be happy with the new rummble of your car and the extra power
I started with nearly the same mods as you have (P1SC at 5.5lbs, cat-back exhaust). I added 1 7/8" American Racing (ceramic coated) and catted x-pipe.
I went from 490 rwhp/450rwtq to 532rwhp/428rwtq, both on a Dynojet. Picked up HP, but lost some torque. The throttle response changed drastically for the better!

A stock engine will see gains of 20+ HP, forced induction a good bit more.
