Most of those Mickey Mouse manifolds are garbage. I personally had one shiny top mounts on my 240 and fitment was an issue, to start. The turbo was too big and the manifold leaned it too much towards the strut tower. Solution, modified the collector and leaned the turbo back towards the exhaust valve cover. Next issue, I don't use tial wastegates, but I have a love for the hks 40mm pieces, so i modded the dump area to suit the HKS gate (bad move).
At idle and normal driving, everything was happy. But when I took for long hauls (20+miles) and put some thrust through it, it cracked and I welded and braced it and it cracked some more. So I snatched it out for the last time, broke down, and my friend who's really good at making manifolds make me another @ the cost $900+. He's expensive, but his work makes up for it and no more labor loss and repairing junky manifolds.
