Hey guys. Thanks for all of the information and perspectives. I've confirmed that my car has the correct 4 speed exhaust with 2.5 inch system necked to 2 inch at the manifolds. I'm still debating what direction to go but am leaning toward a set of AR headers. This will be a fall project and I'll let you know how it goes.

Another vote for Headman headers. I cut the ball and socket off and put vband clamps on to connect to my GNM 3" side pipes. I used Earl's gaskets and stage 8 header bolts. I've had them on my car for almost five years now and no header leaks, no header bolts loosening and nothing but sweet music.
It was cold that day so the puffs of white were H20... now to be totally transparent the compression is 10.5:1 and the cam has .510/.520 lift and a duration of .230/.236 on 110 LSA...
