Review on Dorman 674 860 Drivers Exhaust Manifold by Justin Munajj

Revainrating 5 out of 5

Perfect for exhaust and emissions

Matches my 2002 GMC W3500 Forward nicely. The only thing I would suggest is that any time this driver's side manifold is replaced, the exhaust pipe that attaches between the intake manifold and this manifold must also be replaced.

Pros
  • Consistent test results
Cons
  • I'm worried
