Not sure on when you plan on installing this if you buy it, but it should still be covered under warranty for another 8 months or so. If you're not running a monster turbo and you take the precaution of bracing the manifold in a couple spots I wouldn't worry about it cracking. Although it looks similar in materials and workmanship to an SS Autocrap manifold it happens to not be one, there are a few people running this manifold en e30tech and I have yet to hear of any of them cracking. It's a risk no doubt but shoot an offer that will make it worth the risk... you never know. BTW the OP is my buddy and I have the same manifold that I will be putting up for sale. We bought monster turbos that do not allow you to run a valve cover with this manifold.
