Perfect fit. Wr ground off the "Made in China" on each side. But, actually a good quality casting, that should last a long time on this 379,000 mile Ford diesel 7.3 engine.

Dorman exhaust manifolds for a 7.3l dieselLow quality doesn’t even begin to describe these castings. The first two I got I didn’t even attempt to install because it of how thin the casting were and it looked like someone was just learning how to use a grinder where the casting were “cleaned up”. When I torqued the manifolds to factory specs the driver side one cracked so I grabbed the other crappy one that I didn’t send back yet guess what that one cracked also. So what did I do is sand blasted the factory one with 160,000 miles of New York winters and reinstalled it guess what the rusty old one didn’t break under the torque specs. Dorman needs to take a look at their product because it makes you wonder about the quality of the rest of their parts. I have never left a review of a product but this part was so atrociously bad that I hope to save someone the wasted time of dealing with this product. I just hope that the passenger side holds up because the factory one was not reusable. I feel amazon should no longer offer this productI would like to also say that amazon did quickly send me the replacement set and refunded me for the three that I returned.

A kit is not a kit when it don't come with the mounting boltsThis should have the 8 bolts included. I had to use a sawzall to cut the bolts between the manifold and head on both manifolds to get them off. Then I used a stud remover to get the cut off bolts out.

The manifolds bolted right on it some of the other reviews I read said that it didn't come with the gasket the product for me came with everything pictured. Excellent product and excellent fit on motor

My 2003 F350 7.3L has leaked exaust since i bought it with 90,000 miles. Now with 320,000 miles and the doorman exhaust manifold went on great. Only thing is the gasket shown in the picture did not actually come with the kit.

I purchased this as a direct replacement of my factory OEM manifolds. These manifolds have very bad exhaust restrictions. After first set install my truck was back in the shop 3 days later with a exhaust leak. Manifold failed with a crack by one of bolt holes. Removed cracked manifold. Installed new one. Snugged up all bolts and went back to tighten down to factory torque specs. Before I reached torque spec on first bolt the manifold cracked. Removed another cracked manifold. Installed my third set. Did not tighten all the way to torque specs. So far so good. If it fails I will go back to OEM.
