Review on Dorman 674-675 Exhaust Manifold for Improved Compatibility with Chevrolet/GMC Models by Carnell Bollwitt

Revainrating 1 out of 5

Do not buy this title!

This after sale cast iron replica sucks! Will it fit? Yes it will. Will it crack in less than a month? Yes it will. I recommend using a head tube that sets the pace. It fits like a charm and bolts onto your standard cat with no modification. Plus its 50 state rights and give you more bandwidth. (3 to 4500 rpm) I've had the pacemaker on my truck for about 4 months now and it's perfect.

Pros
  • Automotive
Cons
  • Infinitely slow
