Review on Dorman 674-934 Front Exhaust Manifold for Infiniti/Nissan: Enhanced Compatibility & Performance by Kevin Lawson

Revainrating 3 out of 5

Nice replacement but be prepared to change the bottom 6 bolt holes to match your existing exhaust.

Got this for a Nissan Quest 04 minivan I was working on that had a large crack and exhaust leaking. I REALLY had to drill and enlarge (6 bolts) the holes in the bottom where it connects to the catalytic converter so it can be attached. It took too long to screw it to the catalytic converter. I don't know why they don't have more accurate screw pattern sizes, but I get it.

Pros
  • Heavy Duty Construction - Durable materials resist warping, tearing and leakage for long service life.
Cons
  • Something else
