Review on 🧰 Dorman 674-937 Exhaust Manifold: High-Quality Replacement for Select Models by Will Murphy

Revainrating 5 out of 5

Glad to see a complete kit for this very common problem!

The header needed the same secondary air rail repair as the factory install but it didn't work so they all break. My guess is if you order half a million rails that turn out to be defective, you bend the headers and pry the rails into place. Too bad it only takes 5 minutes with a cutter and jig to line it up and sand the radius and bulge on the underside of both rail mounts. Great product, we recommend not sanding the manifold to fit the rail, use an old gasket to mount and fix the rail!

  • Dope πŸ”₯
