Very Unhappy with "Flo-Pro" Exhaust...

I just got done installing my Flo-Pro 5" exhaust system and have discovered that it has a very loud terrible drone to it.

It also slightly rubs on the spare, and rides on the side of crossmember under the transmission

Before this system I had a straight pipe that exited in front of the back tires, I could not even hear my exhaust (have Dynamat Extreme on whole back of cab) unless I was realy on the go pedal.

I plan on trying to rework the far front exhaust hanger so that the exhaust won't press on the cross member.
For the drone I was thinking about a Donaldson resonator or muffler, any recomendations?
I was also thinking of just putting a piece of pipe in place of the muffler (never could hear the exhaust with my straight pipe and Dynamat) but don't want to p*ss off the law or the neighbors...

Is it just me or is this Flo-Pro system not very well engineered?
