Drone zero's at 80 MPH!Hope it makes you as happy as myself. There is hardly any Drone and you can carry on a conversation while driving at any speed. I hope this helps and am very happy with the sound. It will Purr Like a Kitten on steroids! I am very happy with this system and would recommend this system if you want a Truck to sound like a Truck! Next will be the Cats and then Headers and then a New motor will be installed.

And install the 2-1/2" Exit Pipes and tighten Clamps but do not Finish! Install the Tips and use a gauge like a piece of wood to angle them the way you like.Then go back and tighten everything from the Tail tips back to the 3" Main Pipe that attaches to the Cats. Install your Muffler per the diagram that comes with your system. Install the 3" Diameter section of Pipe, and stick into the existing hanger. Loosen and remove the Nuts that attach your existing system to the Cats. I found this to help the removal of your existing system is to cut the Tail Pipe assembly right behind the existing Muffler, and remove. Spray all the affected Nuts and Bolts with a Penetrating oil, WD, kROIL, ETC. Start your truck and let it get to running temperature which will help with Bolt and Nut Removal. Reading and understanding the instructions this thing went in in less than 2 hours and I did it in my Garage, with Truck on Jack Stands.
