i just ordered my upr o/r x-pipe and its going on as soon as i get it. anyways, i'm gonna be doing it myself in my garage with the car on jackstands and was wondering if you guys have any advice on the install in general? i know to soak the bolts with penetrating oil the night before, using the jack to support the stock h, but is there anything else? like whats the best way to attack stubborn bolts, as well as the manifold bolts?
