A good deal for the money but you may need to purchase seals

I bought this part for my '98 Isuzu Oasis. The price is great and the part fits my car perfectly. Gasket between manifold and cylinder head is ok. If your car is like mine, you need to go to Honda and buy gaskets that fit between the header and the exhaust pipe. The ones that came with this product didn't fit my car. Overall, though, I can't complain that I had to buy two $5 pads when I saved over $200 on this part.

But nice replacement.

Looks like a decent replacement, time will tell. A problem with this kit is the 2 o-rings that go to the downpipe between the manifold and it WILL NOT FIT. They are also VERY cheap. I had to reuse the ones that were in it. It's a bit worrying and I hope it's sealed. If that fails I'll return it and just order a header customization for it. UPDATE 27.05. DO NOT, REPEATED, DO NOT USE the cheap and extremely soft brass nuts that come with this manifold. I had to take one off today due to one sideโ€ฆ

Pros
  • Manifold

Manifold fits perfectly on 1996 Accord EX, wrong size lower gaskets, great price!

Having installed many of Dorman's products as a mechanic I can say that the price is almost always good but fitment can vary widely on many of their products. This header fitted a 1996 Honda Accord EX perfectly, I was able to use the original heat shield as the Dorman has sharper edges and I like the look of the original better. The original heat shield fitted well. The only complaint was that the drain pipe gaskets were not the right size for my application as stated by other reviews. Knowingโ€ฆ
