Stack and frame flex (when off-roading)
I want to put a single stack on my truck. Nothing big and nothing fancy. Just a flat black 4in stack.
I would build the piping under the truck so the exhaust goes outside the frame (just after the frame goes up) and then in the bed, in the very passenger side corner.
I really need it in the corner because I need that 8' long bed often.
Should I put one or two flex-pipe on the exhaust under the bed ?
While off-roading I can see as much as 3 or 4 inches of twist in the body line of the truck. I'm affraid that it would rub against the stack and/or break it.
Any suggestions ?
