i plan on going with pacesetter/ory combo here shortly, i had a couple questions though

can cat's be added to a ory, just for emissions test day? whats involved?

can GM exhasut gaskets be purchased at a local parts store?

Is anti-seezed used on headers bolts and spark plugs?

i do plan on changing plugs during install, and buying the corvette rear o2's... anything else im missing?

Thanks

you can re-use your stock metal gaskets. the pacesetters will come with these cheap paper ones. they come apart over time.
most people dont use antisieze or loctite on the bolts. just make sure to torque them in the right sequence. 12 ftlbs i think it was.
you might want to just buy the y pipe w/ cats.

I'd use anti-sieze. Anything that's being threaded into aluminum gets some before I install it.

+1 on anti seize, also after you torque the headers down, run the car for 20 or so minutes and retorque them...and you could just weld them back in and cut them out afterwards...or clamp em' whatvers easier for you
