Hey. I'm Jeremy with 1A Auto, and this is a 4-liter Jeep exhaust manifold. As you can see, it is a stainless steel exhaust manifold with the flexible sections on the front and the back. It has the proper exhaust flange to bolt to the cylinder head and has the proper flange for the stock exhaust system on the bottom. It comes with the gasket set, including the donut gasket for the bottom, and it even includes the two bolts for the bottom flange because the original ones often break. Once again, it is 1AEEM00147.

Istall was pretty simple and straight forward. Everything fit and bolted up nicely. It's a lot better quality then the original manifold. My suggestion is to light sand, acetone bath and then apply a few coats of high heat paint to protect the manifold. Also if you had really bad cracks I suggest that you replace your motor and tranny mounts or you're going to be in the same boat again with a cracked new manifold.

I have been extremely happy thus far, one month out, with my purchase. I was amazed at the free shipping and quick delivery. The manifold bolted right up perfectly and it is very nice to have a quiet jeep again. The gaskets, lower bolts and flange round gasket fit well. Overall I am very pleased with product and the service. The site was easy to navigate and find my product. Thanks!
Nicely constructed

Best price out there, manifold fit right, though I did had to push the exhaust pipe to the right a couple inches from where it originally was,but the rubber hangers allowed it. and the exhaust flange gasket that was sent with it was too small for the new header so I used the original that worked fine. The gasket was good and thick, sealed well.

Seems a little thicker metal then the one I took out, pretty quite exhaust now. Bottom bolts were the worst to reinstall!

I ordered this to replace the factory header on my 96 XJ 4.0. It was a direct fit with many improvements. Gaskets all fit, including the flange gasket. Steel seemed thicker and overall a better construction.
Hands down, I would not hesitate to buy anything from 1A Auto.
After looking at several manifolds that looked similar and reading 10s if not 100s of reviews, I settled on this one. The fit and finish is very nice and I am very happy with my decision. The only reason I gave it 4 stars instead of 5 was because of the gasket. I had to trim two of the bolt holes to get them to line up properly. Thankfully that was a simple modification. The manifold lined up extremely well and the flange was the exact thickness. Thank you A1!
Parts you can count on to fit.

Had a cracked exhaust manifold. Read lots of reviews on replacement manifolds on all the different parts sites. Read lots of horror stories about how some people's manifold did not fit for one reason or another. I had to have my manifold fit the first time because it is our only vehicle. The 1A Auto manifold fit perfect my 1998 Jeep Cherokee Sport 4.0L. Shipped quick. Would definitely recommend to anyone.

Nice product. Poor packaging.

It's a quality part and a good fit. My only complaint is about how it was packed. It was partially sticking out of the box, and the gasket was a little bent.
Great product, poor packaging.

Great manifold. Packaged very poorly. When it arrived there was a hole in the box where the end of the manifold stuck out as well as the gasket. The gasket was ruined and I had to buy another one. 1A Auto did refund my money.
Perfect fit

It was a perfect fit!
Installation went smoothly.
The Gasket lined up to the Studs.
No more fumes in the Cabin and performance seems slightly better.
Hoping gas mileage will improve without the crack altering the exhaust air to the 02 sensor but haven't had it out on the Highway yet .
