Well, Once again the wife and I took another 9 hour round trip over to the Pendelton, Oregon area Friday to pick up the dually after Diamond eye made an exhaust kit for it. I didn't get a chance to talk to the foreman as he was headed out to pick up another truck. Hopefully soon enough they will have a kit posted on their web site and be available for sale. Now that the truck is home again, I can continue to play with it. A few more LED lights to install an set of bed rail caps to install also. Then the next phase of the project starts and that will take more money and time. Basically I wound up with a 4 inch straight pipe all the way out the back. It looks like it has a 6" chrome tip on it. That chrome tip must be good for another 50HP alone!! (smoking whaa???) I didn't get any details on the down pipe or other mods, but it does breathe easier. Then I fought a 30 MPH head wind all the way through the wind surfing capitol of the world and got about 8.6 MPG on the way home at about 75 MPH.
