    Comments about Dorman - OE Solutions Exhaust Manifold Kit:

    This seemed like a good deal at first... It comes with everything you need to do the job. The trouble is, its been on the truck only 3 years and it split almost in half. I don't dare drive the truck because if it breaks I'll need to get towed. The break is over where the exhaust pipe connects to it so if it snaps off the pipe may drop and it will be like running straight headers. Don't waste your money on this junk. Pay a little more and get a better one. Hopefully there is one out there. I expected better from Dorman.

    • Reasonable Price


    • Doughnut gasket leaks
    • Should have metal gaskets

    Comments about Dorman - OE Solutions Exhaust Manifold Kit:

    Reuse the factory doughnut gasket as the included one leaks. The factory manifold gasket is metal but the one included is composition and will not last as long but does not leak initally. You should probably buy the good gaskets but the manifold itself, which is made in China, is a good piece.
