I have a 1990 xj with a 4.0. It has the original exhaust on it from the factory with that intake heater thingy. I removed the duct work tube going to the intake box since it really isn't needed.
My question is, can I use an exhaust manifold made for a 1991-1996 as a replacement? The only difference I know of is that they don't have the intake heater. Anything else?
