Package arrived promptly. Manifold was made well.
Mike (PA) | March 18th, 2023
Overall the manifold fit ok. When sliding over the 2 exhaust studs in the head it was hitting on the water pipe below it. I pulled the manifold and ground down the bottom edge to get it to clear without hitting. The up pipe gasket that it comes with is junk and I wouldn’t use it.

Fit as described. Works great! Gaskets were correct as well. Just be aware that this does not come with a heat shield so if you’re updating an older duramax from the pinched off manifold the heat shield will not fit on this manifold. I would also recommend buying new bolts for the up pipe as most the time you’ll break or strip out the stock ones on your vehicle.
