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.

The problem with that is that many pulling associations are following DHRA rules or modeling their own rules after the DHRA rules. Whether its a full on Modified truck or a Work Stock puller according to DHRA:

"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."

for a competition rig, definately do a single stack w/ one 90* bend. better performance than restrictive duals

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.

two 8inch stacks with purple flappers along with 5inch duals with yellow flappers and maybe a 3inch hood stack with a pink flapper

one 90* bend as in one 90* bend coming up through the bed and straight up...

vs. those hokey single stack kits that have three 90* bends in them

I like the look of Dual stacks. But nothing looks better then black coal shooting out of a single stack.
