After install, the three flange to head-pipe brass nuts would not stay torqued. Rattled loose multiple times. After re-torqueing many times, the stud threads became worn. Had to remove manifold, replace studs, and use new quality nuts. Lock washers might have helped prevent this (?)

Fit perfectly, just like OEM. Had all necessary hardware and gaskets to do a proper install. No muss, no fuss, bolt and go.

so I ordered it online because it was cheaper but it cracked after 3 weeks or so and had to redo all the work all over again, besides the flange gaskets it came with didn't fit, had to go find the ones that fit an extra 10 bucks! went to autozone and got a new one for $132 and some change and apparently its a Dorman as well hopefully this new one that I got from the autoparts does not crack also or I'll have to find a better quality one that's an exact fit.why didn't you just ask for a replacement you ask, well I need my vehicle to run and can't have it sitting since I need to get to and from work and all the exhaust smell and fumes coming from the vents are really bad could not stand it anymore....

The Gaskets included did not fit despite the website confirming the part fit. It cost an extra $50 in parts and labor because of it.

Having installed many Dorman products before as a mechanic, I can say their price is almost always good, but the fit can vary greatly on many of the their products. This Manifold was a perfect fit for a 1996 Honda Accord EX, I was able to use the original heatshield, since the Dorman one has sharper edges and I like the look of the original one better. Original Heatshield did fit well.The only complaint was that the downpipe gaskets were not the right size for my application, this is something other reviews have stated. Knowing Honda they probably had slight variations by models and throughout the years on this engine. Dorman should do better at listing the application of these gaskets so I could have ordered some prior to install. I left the original downpipe gaskets in and they are working well.This was the best price around, and a great fix, now my wife no longer says my car sounds like an old lawnmower. I have been forced to park outside for the last few months due to the exhaust noise when starting would wake the kids in the early morning. Now I can finally park back in the garage!

Even though Amazon's own system indicated it would fit my vehicle, it did not. This part is for the EX motor, which has a bifurcated exhaust downpipe. Not for the F22B2 motor that is in my 1995 Honda Accord LX.

I bought this part for my '98 Isuzu Oasis. The price is great, and the part went onto my car just fine. The gasket that goes between the manifold and the cylinder head is good. If your car is like mine, you will need to go to Honda and buy the gaskets that go between the manifold and the exhaust pipe. The ones that come with this item didn't fit right on my car. Overall, though, I certainly can't complain about having to buy two $5 gaskets when this part saved me more than $200.
