Hey just got off the phone with PF and he said the March 31 ending was good. As for the U-haul hitch, I need you to email me a picture so I can email it to him and He'll say if it will fit ( josequervo@bellsouth.net ). He also told me that the tips are a 9 degree angle cut if anyone was wondering. And there is no difference in performance or air flow between the loud or quiet. The mufflers are just packed different. If ya'll have any more questions just post. thanks
