I went to the acura dealership and picked up these 3 gaskets that are for the OEM "A pipe" as well as the gasket that goes onto the top of the header (if that makes sense).

Two of the gaskets for the A pipe look like small bracelets kinda and then the other one is a thicker ring, same diameter that goes at the end of the header.

Basically, what other bolts/gaskets do I need? And do I even need the ones I already bought?

Thanks and sorry if I confused the **** out of you lol

 

That's all the gaskets you need, just re-use the bolts on the current exhaust manifold.
