2003 Suburban 2500 8.1
I installed the 3" dual in dual out on the truck to a factory tailpipe. The spacing was wider than factory but not detrimental and easily overcome. The sound of this muffler is awesome and it handles the big block 496 with ease. The drone in the cab is minimal and very livable. I needed something a little more than factory and got just that (and maybe a little more) with this muffler. Great product!

Great Rumble, less drone
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.

Truck/RV Series Muffler
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!
