Dorman 674-685 Passenger Side Exhaust Manifold Kit - Includes Required Gaskets and Hardware Compatible with Select Ram Models

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!

Great quality!! Fit perfectly no complaints at all. Fairly easy to install, great value!!

This item works well. It came machined flat, holes aligned correctly. I bought both sides, driver side gasket was damaged but everything else was fine.

Fit up was as expected . I also bought the matching bolt kit. Would give five star however the bolts for the manifold to exhaust pipe connection had shoulders instead of all threads so wouldn’t fit. Had to purchase different bolts that would fit.

perfect fit...a bit heavier than the oem

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.

Lasted 2 months. Now the ticking is worse than before it also warped and caused the stud to strip my block. Don’t waste your money!

Exhaust manifold did NOT fit 2016 RAM 1500 5.7 Hemi. I had the infamous "hemi tick" caused by sheared bolts in the exhaust manifold. It was the rear-most two bolts, on the rear-most cylinder, on the passenger side. After having the bolts welded-out by a pro welder (good luck drilling - it's a bear!), I used this kit and thought I would replace the gasket, manifold, heat shield, and the new exhaust line bolts. The gasket and heat shield fit fine, as did the new ex-line bolts. The new manifold holes lined-up fine with the old manifold. But upon placing the new manifold onto the engine, the manifold-to-exhaust line connection didn't fit. The new manifold fitting on this kit was just a bit too wide to fit into the exhaust pipe opening. It didn't "go in" to the exhaust line far enough. This left the manifold bolt holes all less than a centimeter misaligned from the engine block holes. I used the old manifold instead, along with the new gasket, heat shield, and a new set of Dorman manifold bolts, and it worked just fine. Too late to return the new manifold. BUYER BEWARE! I'm sure there is a less expansive way to get a new heat shield and gasket, and you can probably re-use your old manifold (which is already heat-broken-in to fit better!). For me, I'm just glad there is no more "tick tick tick tick"!! Good luck!

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 👍

I installed this myself and just over year ago and it’s still holding up, no hemi-tick

Seems to be of equal or better quality than the factory supplied manifold. perfect fit and went in easily. so far no issues. Highly recommended as an alternative to buying OEM.

Great price good product

parts fit perfectly.Delivery was on time .Very satisfied with the product and service
