The Boss Lady's truck is getting sucky milage and I suspect the exhaust is holding it back. She pulls a big horse trailer and I pull a 26 foot gooseneck occasionally. Loads are usually light because Dodge can't build an automatic transmission. It's completely stock (no tuner) except for a aftermarket fuel pump/filter that was installed because Dodge can't make a decent fuel pump. I have a K&N air filter that will be going on soon. I would really like to put dual stacks on it but will prob get overruled on that idea. Can a decent exhaust be fabbed using off the shelf parts. There is a Fleetpride store near me if parts are available there. I'd like to come straight off the turbo and go through a low restriction muffler (she already ruled out straight a straight pipe system). What size pipe would I need to come off the turbo. I don't think there would have to be any bends in it except where it came out behind the wheels. Anybody out there have practical experience in doing this? Pics would be great if you have them.
