Review on Dorman 674 977 Exhaust Manifold by Marc Gallner

Revainrating 1 out of 5

Questionable welding quality

They say you get what you pay for, and here it is. Not installed yet but had to spend time grinding the weld on the flanges attached to the cylinder head. The welds were so thick that they protruded into the pipes, restricting exhaust flow and affecting engine performance.

Pros
  • Rugged construction, built to tight tolerances for dependable durability
Cons
  • Boring packaging
