Right on! I would put a flex pipe somewhere along the line aswell so your not stressing that V-Band. It is going to see a lot of heat and the pinch welds that hold the band to the rings are typically shitty.
Also what I mean by the three stage (or two as some call it) paint isn't how many coats apply. You would have to spray a base (background colour), mid coat (metallic gradient) and clear. the mid coat is hard to do well because the angle in which you spray it and how many passes over the surface changes how it looks.
