Ok lets see, 5.9 Cummins, inline 6 cylinder, so you gonna do a split exhaust manifold and do duals. Last time i seen them done was on an old Chevy PU, sounded like a ****** off bummblebee, sorry Russell, one 6" stack and see if ya can fill it, if ya can put a flapper on it to keep the rain out.

"Exhaust:
All vehicles must be equipped to direct exhaust upward. The exhaust must exit rearward of the driver's compartment. If the muffler or catalytic converter have been changed from stock, two 3/8 inch diameter bolts must be placed through the exhaust pipe in a cross pattern within one inch of each other as close to the turbo as is practical."

jfaulkner, i guess i dont understand the big deal. Are you driving the trucks? Who cares what other people have on their trucks? I could care less what someone elses truck looks like personally. just my 2 cents

Most pulling associations will not allow a turn out or a flapper. The exhaust has to be straight up, open, and cross bolted. This is for tractors or trucks.
