this happens when you are stationary and the engine is above idle speed or only when the car is moving and the engine is above idle speed. what else did you touch/disconnect/adjust/move/etc when changing your exhaust gskts?

anyone else have any ideas as to what it could be? another thing to note is it chirps faster as the engine speed goes up, I am going to go outside to see if its only when I rev it quickly or even if i just lightly press the gas and slowly bring the revs up

I had a cricket once, and it turned out to be the throwout bearing. I'd say it's a long shot in your case, but does the clutch being in vs. out change the chirp?

no it doesn't change Chirps even with clutch engaged, also if I gradually rev higher it doesn't chrip but if I mildly or quickly rev it, it will

Could it be a loose baffle in your muffler, I know that can cause chirps.

You have a exhaust gasket leak. The chirp is what it sounds like if you worked on your header there is a chance there's a leak and it in conjunction with engine speed. Did you reuse your old gaskets? Did you knick a gasket ? Did you tighten them all down ? Your chirp has to be rotational or ehaust in nature.

Sometimes new gaskets have flaws so that could be a issue and sometimes the nuts back off after after the initial tightening. I know on my car when ever i swap manifolds i drive for about 20 miles then check and tighten as needed usually one or two that are loose
