I personally chopped the exhaust off from the 3rd cat back. Welded in pipe to the stock location of the muffler. Welded in a flow master 40 series single in dual out. Ran pipes to the back and tips. In the cabin. Can barely hear it. Outside the truck it sounds nice and aggressive. The v4 drone is there but I use my radio in my truck and don’t hear it that much honestly. Sometimes forget it’s there unless the radio is off.
