I need some advil just from looking around for 10 minutes. Who the hell came up with the routing? It's like they tried to make it complicated.
There was a thread months ago on someone fabbing a set upgraded inlet pipes and I remember him saying what a pain it was to get to the rear inlet pipe. Not sure if anything ever came of it but there were some good pics of what the inlet piping looked like.
