Review on Dorman 674 185 Exhaust Manifold Kit by Jeremy Byard

1993 F150 4.9L. The exhaust was leaking for a while. and the exhaust slams into the OEM manifold. They fit and worked perfectly. The old tubes fit perfectly. decent quality. Not great, but decent. There is a machine cut with an acute angle. causing a stress point and a possible crack point. But I didn't want to spend a day in a junkyard battling the heat and wasps to maybe get a good used one. I was very happy with the role. Use a one-piece gasket for the inlet and outlet - one that is multi-material, preferably metal on the outside. They fail less often than two-piece seals. Don't just replace the exhaust part or you might try again soon!
