Will an exhaust manifold from a 94 4.0 fit on a 99 4.0?

 

IRONNNNNNY....... Yes. I just pulled one from a 99, for my 94, just make sure you don't have any cracks in it, stick a small flashlight in the collector and look for any small cracks!

 

If you are going through all the work to swap one, I would stay away from the '94 and try and pick on up with the accordion section on it. The '94 are prone to crack, the accordion section supposedly helps with that issue.

 

Well yea, luckily, the 99 i pull my part from ended up coughing up a used apn header that i scored for $40.00 bucks!!! thou im no going to put the ct back on, the weight and movement of the cat and exhaust paired with the heat the 4.0 produces develop the cracks. If your still running a cat on your rig, and dont want to cough up the 160 for the fancy accordian manifold, go the auto parts store and get the $15.00 universal flexpipe and have the shop weld it in.

 

It's not for me, I'm trading it. I have a 2000.
