Review on πŸš— Dorman 674-225 Exhaust Manifold for American Motors / Dodge / Jeep Models by Shakim Yates

Revainrating 1 out of 5

Poor quality and fit

Bought to replace the original header for my 98ft Wrangler 2.5L. The price was good so I decided to give it a try. The first problem concerned the intake manifold. The intake manifold is located above the exhaust manifold on its underside. First I mounted the exhaust manifold, which was a good fit on its own. When I started to mount the intake manifold, it didn't fit properly between 3 and 4 cylinders. The block has two mounting pins that line up with the two inlet lugs. The tongue on the intake interfered with the exhaust manifold so it wouldn't sit. I fixed the problem by taking a file and sanding down 1/8 inch of the bottom of the lip. The second issue is the thickness of the mounting flanges compared to standard flanges. The flanges are about 1/4" thicker than the original unit, so 1" x 4" thicker than the inlet. This is a problem because the outlet and inlet share a common bolt in two places. When I made the tightened the nuts the exhaust was tight but the intake was still loose. Make up for the difference in thickness. The third problem is an exhaust leak. Just 1 month later the manifold on cylinder number one cracked. It still runs but needs repair This is a tedious repair. Save yourself time and hassle by saving yourself time and hassle with another product! I should have listened to the reviews. Haven't tried it, haven't even looked at the warranty.
