I took me some time to convince Dabeast2 to put them on his Bee and another friend on his 496 67 Plymouth last year both thought they were a little loud first drive then they both swore they mellowed right out??

When I had mine installed a few years back guy that put them on for me (h pipe now an X pipe) said take it for a drive when I came back he was shaking his head. I said what. He says I cannot believe a 3" straight through mufflers can be that quiet. I said well that is what they advertise!!!
