exhaust outlet diamiter? for zj

[98zjstroker]

ok guys.... ive had my 98 grand cherokee 4.0 for over a year now and have to change one of the freeze plugs cause its leaking. now in order to do that looks like im gonna have to remove the exhaust manifold. so im going to just get a set of headers(i wanted to anyway this is just an excuse for me to). i want a direct bolt on cause it is a daily driver and cant be out of a car while trying to modify and custom something together. the one im looking at has a 2 1/8 outlet diameter and want to know if that is the stock size for the down pipe....ie will it bolt right on without modification? been trying to find the oe size for the outlet diameter with no luck. please help. thanks

ok so i figured out the first part to my question....in case anyone was wondering 2 1/8 outlet is the stock diameter. now for the next issue. before i even attempt it i want to know if anyone has done an exhuast manifold/header install and could tell me if you can just lift the jeep and remove/install from the bottom or do you have to remove the intake? i have only found one video and it showed you taking of the intake.
