Allen Baum –
I recently purchased the Dorman 674-685 Passenger Side Exhaust Manifold Kit for my vehicle, and I couldn’t be happier with the results. Installation was a breeze thanks to the precise fit and comprehensive instructions included in the package.
The build quality of this manifold kit is exceptional, and it feels durable and sturdy. After installation, I noticed an immediate improvement in engine performance and a significant reduction in exhaust noise.
Not only did this kit solve my exhaust manifold issues, but it also exceeded my expectations in terms of durability and performance. The price point is also very reasonable compared to other options on the market.
Overall, I highly recommend the Dorman 674-685 Passenger Side Exhaust Manifold Kit to anyone in need of a reliable and efficient solution for their vehicle’s exhaust system. It’s a five-star product all the way!

The absolute most unprofessional and inconsiderate vendor on Amazon. Waited almost two weeks for part only to have them tell me its not showing up at all and no explanation whatsoever… just … crickets !!! Stay away from Doorman parts, they absolute suck!!

I had an exhaust manifold leak on my 2018 Ram Hemi right passenger side. I purchased this manifold, came with gasket and heat shield. Bolted on nice, torqued down and no more annoying exhaust leak. I recommend this product 👍

Replaced a warped oem with this, checked with a straight edge and was near perfect. I used a felpro gasket not the one provided. Would recommend.

This doesn’t include the necessary bolts for manifold to head which are the most important!
Most (95%) replacements are done because the rear manifold bolt fractures.

Loved how it fell into place

I had to replace broken exhaust manifold bolts, so I decided to replace the manifolds. The old ones were warped but this fit perfectly.

Bought this and installed it on my passenger side. Doesn’t hurt to have an extra pair of hands to install but can be done by yourself. Recommend a small cheater bar when removing the screws.

No more leak! Everything fit perfect on a 2017 Ram 1500 5.7l.
