ok, this is my first post so dont go to hard on me.
i want or rather need to get rid of the factory exhaust manifold on my 02 tj, with the 4.0, after looking around i discovered that headers specificaly for my model year can be pretty pricey. now i really dont want to spend that much on a header for my DD, but i do want a header. the interesting thing is that headers for the 99 and older tj's are rather affordable, the difference being that they dont have provisions to mount the converters right to them (and that is not a big concern for me) and they only have single outlet. Now i know i would have to make provisions for the O2 sensors in the header, which is very do-able, my question is can i mount an older style header to my newer 4.0? Would i have to modify my intake or anything else? (besides getting some custom exhaust work done)
I think it would work because to my knowledge there hasn't been any major design changes to the 4.0 in years, and im pretty sure the heads haven't changed since 1991. But i would rather ask than spend money to find out it would not work. Thanks everyone!
