need help with my setup

first of all I measured my pipe after the y and its 3 inch which is cool.

I am running a ported out tpi system. its a 350 with 305 heads cut with 1.94 valves. a lt4 hotcam and 24 lb injectors. I also had the throttle body ported out to a 52mm and a adjustable fuel pressure regulator.

I was wondering what type of exhaust I should run to compliment the upgrades I have done to the motor.

what size primaries do I need in the headers. would 1 1/2 inch work or do I need bigger

1 5/8" headers or even 1 3/4" shorties, 3" catback.
