My Jeep blew up today. I joined the 0331 club. Does anyone know of an exhaust manifold that fits a 2001 Jeep Cherokee without the cats on it? Since it's got to come out I might as well make some changes. Any help would be appreciated.

 

IMO not really possible.
Technically.
What do you use the Jeep for?

This is if you went to the old 0630/7120 head but kept the stock cast manifold.

What head casting are you putting back in?

 

I have replaced my 0331 head with a 0630 head. This involved changing out the exhaust to match the 0630 config. I had the exhaust shop install 2 O2 bungs drilled in each collector so it still kind of matches the orig 0331 config For the 2 primary sensors. One sensor for plugs 1-2-3 and other sensor for 4-5-6. The down / crossover pipe had to be changed to the 0630 config .Then i had 2 more O2 bungs installed behind the "resonator/ 2nd cat" but in front of the muffler. I then extended the O2 sensor wires to mount way down there so i run a stock 01 sensor config that throws no codes. I had already done the coil rail eliminator mod so that was no longer an issue. The new motor is a 97 stroked to approx a 4.8L. It was not very difficult , did all the work myself except the exhaust welding....no issues and the 0331 head and exh would have been useless on a stroker

 

Sorry for the long response time. I appreciate the feedback. I went with a reman from Powertrain Products out of Maryland. I'll take the 7 year unlimited mile warranty. It seems that they put a 0331 back on it. I brought this up to the salesman and he assured me that all of the bad 0331's are all gone and that the new ones are better and do not crack. I guess I have 7 years to find out. I'm just in a bind right now and need to get her back on the road as soon as I can. She's my daily driver but I also use her for work when the need arises . I'm driving the work van right now but the van doesn't have 4 wheel drive and that's when the XJ comes into play. I live on the OBX and need her for the sand land jobs we have going on. In the future when I decide to do the head switch it will take a custom exhaust to make it happen?

 

I dont know if you need a custom exhaust but it will need to be a "modified" exhaust. If you got a 7 year warranty on the engine/head and they actually warranty it, thats fantastic. The body will be almost 30 years old by then and i doubt you will be re-engining a jeep that old especially driving in that salty sandy environment
