Dorman 674-272 Exhaust Manifold Kit - Includes Required Gaskets and Hardware Compatible with Select Toyota Models

I'm hoping this manifold lasts, I purchased the same about 11 yes ago the cast iron had deteriorated where the manifold pipe connected causing an irreparable exhaust leak thus I had to replace it

Good quality piece. You can tell they used a sand cast or something similar to mold the manifold but they did a good job making a smooth contact surface for the head and exhaust and there were no cracks that I could find. There were some burs on the inside of the ports which I filed down a bit just to avoid possible build up (not necessary really). As for the heat-shield which I noticed some said looked like tin that was beat with a hammer, it was still in better condition than the factory one I had and there were a few areas where you can see that metal overlapped during the stamping process, but I didn't noticed anything like being crushed or hammered upon. It dose its job. I was also skeptical of gaskets at first but upon inspection on arrival, they were on par if not better than OEM gaskets and other aftermarket gaskets I had already used, the studs were a nice touch as I was constantly fumbling with bolts to hold my exhaust to my old manifold. I do recommend buying a stud set for your head if you don't already have them (I did not due to having just replaced it). When you fire the vehicle up upon first installation, let it reach temperature in a well ventilated area (which is were you should be in the first place since you're working on a vehicle) as I found oil and other substances that had gotten onto the heat shield and the manifold began burning off and created quite a cloud.(I had taken it straight onto the road and local LEO's thought I had something wrong with my truck)

only a plastic bag around the manifold with a 6 inch rip, no other packing in the box. 1 of 2 bottom O gaskets missing. manifold gasket bent to 90 degrees and unusable upon straightening. An unwelcome delay when trying to fix my primary vehicle.

EXCELLENT QUALITY FOR THE PRICE! After I received mine in the mail I brought it to a local Toyota dealership who happened to have an OEM Toyota 22R exhaust manifold in stock. They allowed me to compare the two and other then the fact that this one is made in China while the Toyota one is made in Japan, you can't tell the difference. As a matter of fact the gaskets that come with this kit are actually of better quality then the Toyota OEM ones. They are slightly thicker and not as easily bendable as the Toyota ones. I would say it took me about 2 hours to remove my old manifold and install this one. I took my time and made sure to slowly tighten all 8 nuts up to 31lbs. All the manuals say you can set them from anywhere between 26 and 34lbs so I decided to go right in the middle. So far all my previous leaks are gone and my engine is running much smoother.I MUST mention that the heatshield bolt holes go completely through so I decided to put a small amount of Permatex 81878 Ultra Copper RTV Silicone sealant around the underside of the bolt head and the underside of the heatshield (around the bolt hole) and a little bit on the threads. I didn't trust just the bolts to make a good air tight seal. Both the OEM Toyota and the Dorman manifold have the holes going completely through which really seems odd to me. My original manifold had the holes sealed either by the factory or by someone else so I didn't expect them to go clear through the manifold. So again, make sure to either plug the holes like I did or if you don't intend to use the heatshield at least make sure to plug them with the provided bolts while using some copper RTV sealant.

Good part bad packaging. Missing a flange stud and two of the nuts. Also manifold gasket was bent due to it being loose in box with the steel manifold and moving all over. Maybe seller can reach out to fix this issue since this was a time sensitive repair.

It worked but didnt look the greatest. 1 of the donut gaskets were missing, which was important to me. Just know they apparently have enough complaints about missing parts that they include a paper that outlines where to look throughout the box & in the exhaust itself for smaller items. My gasket was definitely missing.

Fit perfectly on my 1993 Toyota pickup

Package had all gaskets and hardware. The manifold ships with the heat shield attached and after bouncing around in the box the heat shield was bent on the top. Had to try and straighten it myself. Also, there is excess material along the bottom edge which prevents the four bottom nuts from seating properly when mounted. I had to use a grinding bit to flatten those out. Bottom line...should have been packed properly for shipping and needed it more finishing work.
