I did a lot of research before I bought this muffler. I wanted something louder than stock, but not to loud to upset the neighbors or the police. I would describe this as a mature sound, that is not obnoxious! At first I thought it was too quiet, but it seemed to get louder after a few hours of use. There’s a little drone to inside the truck, but usually only when I’m accelerating. Turn the radio on and the drone goes away. I put this on my 2010 Silverado that I’ve been restoring over the past few years. I’m very happy with the sound. Could it be louder, sure…but I don’t think I’d like the louder noise on the inside if I had gone with a 40 series.

Great mufflers. Louder than expected but the sound is sweet.

This is my 3rd Flowmaster (Mustang GT 4.6 w/Super 44s; Dodge Dakota 4.7 w/ 50 series Delta Flow) and when I sold both of those vehicles recently the mufflers still looked and sounded like new (10+ and 5+ years old respectively). So when it was time to upgrade the muffler on my new project (2003 GMC Sierra 5.3L 2wd RCSB) buying another was a no-brainer ! I cut out the factory muffler, had a buddy stretch the factory 2-3/4" pipes, then I welded a short piece of 3" pipe, slid the muffler over each, band-clamped it together and that was that. The truck sounds wayyyy better than stock, it seems to rev more willingly, it's loud enough to let everyone nearby hear my LS motor sing but not so loud that it's annoying, there's essentially zero drone in the cab, and because of my past experience (they seem to last forever), I'm probably now a Flowmaster owner for life (I look forward to putting one on my next project).
