2004 Dodge ram 1500 4.7 v8. Single 2.5 in and out, single tailpipe. Really has a nice deep rumble that you don't get with flowmaster or others. Quiet at idle. It is reasonably loud only when you are on the gas. When at idle or cruise it seems really quiet. And really wakes up when on the gas only. So far i'm very pleased. Definitely a light rumble at speed but no drone. Makes my little 4.7 sound much deeper and bigger than it is.
Very Heavy construction, definitely expect this to be the last muffler my RV will need. Shipping was timely, this baby and my new headers woke my Olds 455 up!
