Review on Dorman 674 156 Exhaust Manifold Kit by Chris Benton

Revainrating 5 out of 5

Works fine with no problems.

Made in China but probably fine. The head bearing surface is flat milled and the flange processing is fine. I bought both sides to replace my rusty manifold bolts. Instead of wasting time removing rusty grommets from my factory distributors, I made my life easier with these distributors. These headers have the same heat shields as mine. The kit includes a ring, bolts, springs and nuts. For some reason my driver side manifold came with a gasket for both heads and the passenger side manifold came without gaskets. This worked for me, but be aware. They come with a plugged connector that should be for emissions. I didn't need to use them, so I took out the holes with my grinder to open them as wide as possible for better exhaust flow. That's all. I don't have any exhaust leaks and they look almost exactly like the OEM ones. We're lucky that Dorman makes them as cheaply as they come because trying to salvage OEM units would take patience and perseverance.

Pros
  • Exhaust and Emissions
Cons
  • Not sure
