Flowmaster 817615 single outlet cat back exhaust

Anyone running the 817615 single outlet cat back exhaust?
I got one and man it is loud in the cab, terrible drone. The clamps that come with the kit suck, so I added some summit racing larger band clamps and a MBRP resonator http://mbrpautomotive.com/?page=products&part=R1012 and it is so much better, plus it greatly improved the sound. It is deeper and less rice burner sounding. I wish the kit was polished.

 

gottaToy - I am looking to add either the 817615 single exhaust or the 817614 and you are the only one I can find that has used the single. If you could do it all over again would you stick with the single or is it too loud? If you could go back would you have chose the double exhaust? I've heard and read that isn't as loud but still sounds good.
