I was reading a bunch of threads on the manifold crack (after my Envoy just got really loud over the weekend) and found this thread on a header for the Envoy.
I'd rather put on a header for some more money then replace it with the same. + extra HP, is always needed.
How long till one is available for purchase and a final price on it? Will it come with bolts, gaskets and everything needed for direct install? I probably will not be doing the repair till spring, so I have some time. How does PCM of NC go about the "new tune".
Thanks for any answers you have.
