the problem with mine is the flat against the head is warped and 2 of the pipes welded to it are not bent down far enough that they have been put into a clamp to weld and the heat from the exhaust gasses has caused warping and breaking of the welds and warping of the manifold face, it also breaks at the other end of the manifold as well against the 6 stud joint
so yeah general quality control has gone out the window with this one
oh the manifold face is not full stainless either, pipes are borderline as well
its lat outing will be santa pod against my sons Twingo then the manifold is scrap
