Hey guy's, well I have a new 07 dodge 3500 dually, 6 spd, with the 6.7 , 100% STOCK.and I run a hotshot business, so I am always pulling a trailer, loaded about 18-20k, on the trailer. I am getting about 8-10 towing, and 12 with empty trailer. I need a little more mileage, I wish they made the mileage max for the truck, What is ur opinion on things I should do to get it. Now keep in mind, I need reliability, I dont need to be dealing with problems with the regen, or ect, while 1k miles from home. Any Ideas??? Thanks

 

look at the mp-8 for good gas mileage. not sure if its out yet, but look for the smarty jr. not the sr.and before any of that, you need to get an exhaust and an AFE stage 2 air.that should keep you busy for a while.

 

With the 3 catalyst-like things, I bet a straight pipe might be pretty quiet.
