Made a previous video of what this truck sounded like with open Hedman Hedders. This is the complete job. We did it all ourselves. It consists of the Hedman Hedders, a 2 foot section of 2.5 inch pipe, 2 foot MBRP Resonators, 2 foot follow up sections, and a 45 at the end. I got underneath so you can see. WE FULLY WARMED THIS TRUCK UP BEFORE REVVING THE CRAP OUT OF IT.
