I'm going to date myself here. When I was young there was a very good product on the market called "Jardine" headers. Gerry Jardine lives her locally and still produces exhaust systems for vehicles. He took a 6.4 from our lot and tried very hard to build an exhaust system that would work. No matter what he tried the truck made less power on the dyno. I quess the moral to the story is stop messing with diesels!!!
