Just Trying to get a second opinion before I Order
planning to buy:
ARH Race Headers
ARH Catted Y
Corsa Cat Back
O2 Simulators (just planning on pluggin the hole in the Y)
Stage 8 Locking Bolts
Header Gaskets
2 o2 Extensions
Also The car has 78xxx Miles on it, Should I consider changing the plugs and wires? Car is jumpy at idle... Rpm Stays the same, It almost just feels like it misses or something????
I would use new GM header gaskets if you can.
Can't hurt to change the plugs and wires. Why not get some fresh ones in there with fresh mods? I know people go forever on spark plugs, but with how cheap NGK TR55s are, I change them every year, sometimes more often. If you don't foresee any bigger mods anytime in the near future, save some money for a good quality tune.

The ARH Kit comes with 2 O2 Extensions for the front O2 sensors. And you can just put in the rear O2s and start up the vehicle. I just did ARH Headers and I didn't throw any code when I fired it up. The Kit also comes with gaskets that seal well after retightening the headers after a dozen or so heat cycles.
I would suggest getting an extra wideband plug welded into the driver's side manifold. It will help with tuning later down the road.
As other suggested, plugs, wires and poly motor and trans mounts should be on the list.
Don't forget the anti-seize and loctite.

good idea about the wideband, wouldve never thought of that
and the reason for the o2 simulators is just so i dont ever have to worry about the codes whatsoever

The ARH System has bungs for the rear O2 sensors located downstream of the Cats, for the rear sensors you do not need to have any extensions, they plug directly to the factory harness without splicing. There's a reason why ARH's are so expensive and it's b/c of the amount of research and development to have great fitting headers with least amount of issues.
No - just pick one set of gaskets and use them. Either ones will work - only the ARH gaskets will need to be retorqued after some heat cycles due to the gaskets compressing.
Also, unlike other header systems you will not have to modify the dipstick to install, it again slides right in.
Good ls1 headers have thick enough flanges its not an issue.
Definitely get motor mounts, and I also reused the stock manifold gaskets, they no not leak either.
I try to be thrifty where I can, more money for more mods.
