Review on πŸš— Dorman 674-391 Driver Side Exhaust Manifold: Perfect Fit for Chevrolet / GMC Models by Evan Larson

Revainrating 4 out of 5

Fits Trucks. Works great with Manifolds

Fits Trucks. The fitting supplied with the egr is different from the OEM so you must use this manifold with it. I mostly ordered for the faucet because the dealer wants more than this whole manifold just for that faucet. I went ahead and used the entire manifold and it worked fine. It worked because when I took my old one off it was still cracked so the fit was different.

Pros
  • Exhaust and Emissions
Cons
  • Almost OK
