If your peak EGT's really are 1100F, then your tune is leaving a LOT on the table.
If I were you, I'd probably go back to stock headers. Most street cars won't benefit from aftermarket headers until you reach pretty aggressive levels of power.
You are correct, 304. I wanted something drivable with a bit of spunk and great reliability. Mind you its an ej205. Going for a final retune in a couple weeks and we shall see how that changes everything. It wouldnt surprise me if the stock sensor maxed out there.
