New exhaust system....
#11
I dont know about the 4.7l but I have a 3.7 with the super 44 (front reso still on, turn out in front of the rear passanger tire). It has a great sound outside, but it is not loud inside the cab at all. Gives the truck just enough grumble to sound like it has some b*lls, you hear it barely in the cab. Stock set up was way to quiet, I had actually tried to start the truck twice before I had this set up put on. I have a before and after video posted in the forums.
