Its not that loud at all. I just has a very nice rumble to it. Perfect sound IMO. My driveway is right outside the window of my 2 year old son and it doesnt wake him up when I crank it up at 5am.Based on the reviews of the B2 14” Magnaflow I’m thinking it will be too loud for me. Quotes like “it will get your neighbors attention”...hmmm.
