well I had a flo pro 5inch downpipe back kit on m truck with their muffler and a 8 inch tip and after time it got to be pretty annoying so I put back on my 6 inch tip and that helped a lot but still was loud at 2000 rpm and above so I replaced the flo pro muffler which was 23 inches body length and 29 inches overall with a Donaldson m090535 muffler and couldn't be happy, still has some growl to it but not as loud as what it was, much better
