So far, so good!!!
My Wrangler has leaked exhaust since I bought it a year ago. Tried several liquid metal products to fill the cracks and the last one was fairly successful, but there was still a leak. Bought this based on the reviews and warranty, and my Jeep sounds/smells awesome!! I took the power steering pump off the intake, removed the airbox and tube, removed the throttle cable, then left all the electrical connections in place. Took out the bolts and slid the exhaust out from between the intake and head. Took about an hour and a half. Well made product and works great so far. Dan

Jeep 2.5 exh.manifold
Great price on this part. Heavier made than the original. However , the flange was thicker than original , thicker than the intake flange, and that required machining to let the bolt and washer properly hold the manifold set together against the head. Both flanges have to be the same thickness. The intake will not tighten without removal of some of the extra thickness from the new exhaust manifold flange.

Great price
I purchased the exhaust manifold from 1A for about half what it was at the "parts house". I personally did not install it I had a mechanic do it. He didnt have any complaints adout the install and as far as i can tell it works great no leaks. I would recommend this item to anyone. It was also shipped and delivered in a very timely manner.

Much better that original
Much heavier and robust than the factory manifold that was on my TJ. Bolting surfaces are about an 1/8" thicker which causes an issues where exhaust manifold and intake manifold share bolts. Easily remedied by spot facing these areas with a mill or small grinder (dremel, die grinder, etc)

Jeep TJ 4 cyl exhaust manifold
The manifold arrived quickly. It was a good fit, however some modification to the heat shield was necessary to install the top center bolt and to clear the motor mount. This was frustrating as it had to be removed twice. Jeep is very quiet now.

Manifold is thicker than stock
As the title states, the manifold is thicker than the stock one, on the plate specifically where it bolts to the head. The issue is that the intake is now to thin (bolts on with the manifold). The heat shield was also in the way of one of the bolt holes and had to be modified. Ill figure out a way to make it work. The manifold looks to be good quality, despite the flaws.
