The exhaust system is typically the manifold/header, down pipe, flex pipe, cat, resonator, muffler, and the piping connecting them all. I have a header into 2.5" mandrel bent and I wouldn't go any bigger for NA.

Also, when you connect the header back to the head there is a specific torque sequence that you are suppose to follow. Starting in the center and working out at a certain value then do it again to a higher setting. This prevents warping of the head. The connection really does not need to be uber tight either, that is what the gasket is for.
