I was wondering how many of you have installed this manifold and what your thoughts are about it. I was also wondering if the 07 Silverado Classic LBZ is equipped with the pinched manifold. I figure if I have to drill and tap a manifold for a pyro I might as well just install this manifold.

I think its a great product, not too hard to install once you get everything out of the way. If you get one take your heat shield off and mount it to the BD manifold, put it on the bench to reshape it and cut a notch out for pyro port. You'll have to take it back off(heat shield) to mount your new manifold as it is hard to get at all the bolts with it on. :D GB

Very nice product:) . I but mine on when i added the bully dog outlook monitor. Port is already there. Plus, you get rid of the restriction. Do just like gatorbaiter said.
