My HTT 3 piece manifold cracked across the top all the way to the webbing. I had my stocker crack at 150k miles & spent the $400 on the HTT to cure the problem. Now at 170k miles the HTT cracked. I'm confused, stocker lasts 150k miles, HTT lasts 20k miles? Sure doesn't seem to be worth $400. to me. Anyone else had one crack?
