No Worries.....I did not know I was Hating :) I was only pointing out there is a lot more that goes into designing a manifold then just pipe and welds. You will have a serious reversion problem with that Log design. The factory Cast manifold even directs flow :) If you actually flow tested the log manifold you have the picture of you will find it flows less then a stock manifold. As far as cost......I guess you have not priced Inconel.....The cost is *MORE* then 10 times the cost of stainless. When we were looking into producing log manifolds in stainless we were projecting a street price of $800. The fact that stainless will not live at the temps seen in this short of a manifold on a VG30DETT caused the need to go to a material that could handle the temperature and unfortunately the cost of the material forced the price.
