How much would this affect me? I just got back my turbo manifold from Jet-hot, and I noticed that, on the inside of the manifold, there is an area the size of the thumb that has cracked and chipped off. Should I sent it back? I am thinking, that after all the exhaust gas has flow thru the inside of the manifold, the inside will be covered with soot anyway. However, I am just afraid that the concentrated heat on that area will crack the manifold in the long run. What do you guys think?

btw, do they apply the color to the inside of the manifold as well? my manifold is blue on the outside and white on the inside?!?!?
