Sound is great! Little drone in V4 mode but overall a great system. The cold starts have a nice loud rumble but not so much you'll piss every neighbor off

The newer GM trucks have a lot going on with the exhaust, keeping them quiet as can be. I wanted to be able to hear the v8 without it being obnoxious, loud or having a drone at highway speeds. The 22" Magnaflow muffler is perfect, gives a nice deep tone and you can't really tell it's on there until you step on it. Very pleased with the purchase!
