The dinan x pipe is way too expensive and really stinky.
This. I have the turner test pipes and for $395 plus installation labor I have different car. Sounds relatively normal under regular circumstances and then it transforms into a different machine under WOT. I still have the OEM x-pipe and rear section and don't see any reason to change anything else out. If anything, I'm thinking of a BPM Tune just to get the most I can out of the car with a limited amount of cash out the door.
