It's not hard at all but you should have the service manual for torq specs.

just a slideshow, never did a full writeup. That is the Banks header and
it was a (almost) drop in. Almost because I had to massage the motor
mount for some clearance.
Stay away from the cheapo manifolds, those are usually re-welded broken
manifolds. You can get the OEM price from here

Re: 4.0L wrangler: Replace a manifold myself or have a mechanic do it?
Just a followup, but if it's only the gasket that's
leaking you don't need a new manifold, just remember
to clean the mating surfaces and put a thin (smear)
of formagasket copper on the head and manifold sides of
the new gasket. by thin I mean thin, think about how
thick a wax coat is, that thin.

Depending on your year and mileage and state of residence, it may be
under emissions warranty.
It is a pita to replace as many of the parts tend to be really heated
into place. If you are careful and document the parts you need to
pull to get at it, and have a good set of tools to deal with
surprises, it is not a technically challenging task. Be prepared to
lose a few knuckles and improve your vocabulary.
If yours is not under warranty, you will probably want to go
aftermarket...the chrysler units are all, including the alleged
ones that correct the design flaws, a piece of crap. Hesco,
Banks, Borla, Edelbrock have units.

With all of the fun and enjoyment involved in pulling an exhaust
manifold, it would seem to be a waste of time not to replace
the crappy original with a good aftermarket one.
