Got to playing to day an opened up the airbox and exhaust. I cut stock inlet to airbox up to increase opening toabout 4 times orginal, made an aluminim plinuam and enlarged hole behind headlight. After that ran 3 1/2" exhaust from down pipe thru '97 powerstroke straight tru muffler, then over axle into 4 1/2" slash cut stinger. This was my own design as I bought nothing. Pic's are attached.

I love to see what people do to make their trucks better with their immagination and not their wallet. Keep it comming.

 

That airbox will work just fine!
