header swappable with exhaust?

[Streets_of_Fire]

question: i have an S14 with a ka24de, obx headers, and had custom exhaust piping made from the cat back back. if i were to either put back my stock exhaust manifold or buy a DS header, would they still bolt right on?

as long as the header wasn't modified/welded to the cat or test-pipe, everything will work fine.
