Only trouble now is the exhaust. The fitment on the Magnaflow catback is not the best. It hangs a little too low so the rear section rubs a bit on the subframe resulting in a rattle at low rpm (i.e. idle, reverse, or just moving from a stop). We are going to spend some more time tomorrow tweaking the fitment a bit, but I think ultimately I'm going to need to modify the rubber exhaust hangers or source stiffer, shorter ones. The stockers are like marshmallows and allow for a lot of movement.

It sounds really good, though. I'm jelly. Z is quiet as a whisper.
