I am thinking about a diamond eye 4 inch cat back stainless steel system for my 2006 quad cab. Has anyone installed one? How do they fit? Is it loud or especially does it drone. I don't mind a throaty sound but I don't want it to be annoying or drone. Thanks

 

I installed the 5" turbo back kit, cheeper than most, pipe is pipe, looks good, sounds good, I have a muffler that I installed, little to no drone but I have not towed with it yet. I am happy

 

I installed one on mine and we installed a 2nd on my son's PSD. Won't be a 3rd on anything. In both cases, muffler back fitment was less than desirable.
