I was hoping to do it for engine bay clearance, as I have long tubes and they are a pain to work around. And the fact that I'd be losing 20lbs or so on top of my Teksid block swap was just a bonus.
I've got some more researching to do about solid mounts tearing up the chassis. It sounds like the AJE will be plug and play as long as I don't mind solid engine mounts. And the UPR "should" be plug and play, but it likely won't be due to fitment issues.
