Well, since I only drove it over to an eatery and then home, I can't really say. It seems quiet at even speed and in mids but wakes up when you step on it. I ain't really put my foot in it because the roads are rain slick. It doesn't seem as load as the one I had on the 04. That may be due to the fact that the placement of the muffler is further back from the cab on the new'12.
