Hey folks I know there are dual stack kits for this truck, but they use an exhaust box on the top of the bed which is beyond retarded. I also know they don't put the stacks through the bed under the bed on the sides due to the fuel tank being so close to the fuel tank. I know it can he done, but am curious what others have done to be able to run an exhaust pipe closer to the driver side.

Please don't suggest a single stack, or these retarded types of over the bed mounting, I want to be able to put a full sheet of plywood in the back of my truck with the tailgate up.

you understand all the obstacles, you mentioned everything but the driveshaft.... it can be done but needs to be a one off installation, on site only.

One way to make the system easier to do is to split your 4 or 5 inch exhaust and go 3" tubing to your corners... then once you get vertical get back up to 4 or 5 inch for your stacks.

Thanks for the response, wouldn't that only work for a stock truck? Or will (2x) 3" have enough flow to not create back pressure on a 5" exhaust? My truck when im done will be abpit 500hp to the floor and I don't want to mess that up.

Thanks
