I just bought installed a KA SS Autochrome turbo mani and gave it to my cousin who is a welder by profession to cut the flange between the runners with a plasma cutter. He talked to a lot of people and they all agreed that it was not necessary to do that since the flange is like 1/2" SS and if the flange gets hot enough to warp then it will have melted your aluminum head a long time ago.
Anyone have any comments to this???
For $350 you can not beat their manifold. Put flex pipe like said above between exhuast pipe and turbo to limit the torquing. Hell, you could pay to have it welded even if it does crack 10 times or better for the money you saved.
