Regarding fitment, it was pretty good except that the top of the piping going over the rear sway bar contacted the head of the bolt for the rear differential mount at first. We loosened things up again, and shifted them around slightly, and now it has some clearance, but BARELY. Is this normal for this system on a Z?

We drove it around a bit to test it, no rattling detected, so that little bit of clearance was just enough. As for the sound? Awesome, I love it, he loves it =D
