No you will be fine...what headers you going for?
I have an 03 Galant. Will a SES Light turn on if I replace the stock header with an aftermarket? IF it does and I use spark plug foulers on them to bypass the light, will they pass emissions and inspection? Thanks

depends really, My car is a 2000 Fed-spec and the primary o2 is in front of the cat away from the header. I believe the Cali specs have one in the header. Nonetheless, you should probably use the foulers anyway just to be safe.
If you're car is Cali-Spec, Yes. Fed-Spec, No.
If its Cali-Spec you would be best off relocating the 2nd O2 sensor from in front of the second Cat to behind the second Cat like I did. I tried a spacer and it didnt work. So I moved it behind the second 1. Worked like a charm.
I think mine is a Cali-Spec because of the 2 CATs and 2 Fans. The O2 sensor is on the front of the Header. I am looking at the EB headers on Ebay, $84 shipped, not looking for any type of performance just trying it out that's all. I guess I'll purchase that and find a way to bypass the SES Light. All I am worried is if I can pass emissions and inspections in P.A. Since you guys didn't say anything about that I assume I will pass it?
There are 2 O2 sensors on the car, one at the header/first cat [They're Integrated] and another after the first cat but before the 2nd. The first O2 sensor ensures your engine is running properly, & the 2nd O2 sensor ensures your 1st cat/header is working properly.
I bought the same Header, no issues works fine. Now as for you passing Smog, NOT GONNA HAPPEN. It's illegal to remove a Cat, and you will be fined and not pass. Period. You'll have to swap out b4 a Smog test.
Thanks for the Info Ivory.
