my parents are getting me a set of the JBA chrome headers for christmas, and im hoping to get them installed in a weekend. for those who have done a header install on a 4.0, any tips, pointers, general advice to make it go as smooth as possible? im gonna spray penetrant on the manifold bolts every other day this week too let it really get in there.
ill prob do a lil write up on the install and overall gains and a video clip of headers b4/after with stock muffler, no muffler, and a cheap-o 20dollar muffler from pep boys.
i had a truck.
