My truck has nothing but a muffler and I will have to say I hardly ever hear her. Except in tunnels, lol. Unlike you younger guys, which I actually do understand, I love quite trucks and low flying planes!
There is a lot to be said for being under the radar, the less offensive one in the crowd.....the one that "got away" so in truth I'm grateful for you kids. Run that bitch loud, smoke whatever you want so I can glide on by while they attend to you!
Mine, with muff only, has less noise than my first car a 67 VW bug! Amazing ten times the power hardly any noise! Yea Dmax!
