I got the jeep and the previous owner had installed a headers, way too loud for me. This install was not hard great fit made job easy
Well I read other posts, and ordered a Fel-Pro gasket because others said the gasket included was garbage, which it was. The exhaust manifold it’s self was ok, and fit the vehicle as it should. However, the O-ring didn’t even fit the pipe, and neither did the two bolts to mount the pipe to the exhaust collector, one would think since you have both parts that you would check this. Poor quality control!
I replaced my cracked exhaust manifold over the weekend with this RedRock product and am very satisfied. I didn’t give it a 5 star rating for two reasons… 1) the exhaust flange gasket connector to the tailpipe provided didn’t fit on the provided header pipe (too small), so I ended up stripping out some of the inside and reshaping it to work, and 2) the manifold to head gasket provided was slightly off centered on two of the bolt holes so I had to slightly expand the hole area. However the header itself seemed of good quality, fit perfectly, and packaged appropriately.
I had an exhaust leak, ticking, and loss of power. This manifold is working great. The downside was the gasket didn’t fit correct and had to get the correct one from a local parts store.
