Will dual exhaust like flow masters, additives or air injection help? I am not expecting miracles, but I love the car but hate the gas bills.

I have a 2000 5.9L and my mod list is quite large. I was getting 11.9 mi/gal. Once I put a catback system (flowmaster 40 series) on it, i got it up to 12.5 mi/gal. Also, try to get some real good spark plugs, wires and distributer cap. My durango went up to 13.2 after that.

LOL, ok I know thats not funny. The Dodge 5.9 has never gotten good fuel economy. K&N air filter, flow master exhaust will help, but maybe 2 to 3 miles per gallon. The best thing I found is make sure the air filter is clean, you use a good grade of fuel, and you have the proper air pressure in your tires..oh yeah and slow down....I have found that most vehicles get better fuel mileage if the RPM's at highway speeds are run at 1900 RPMs or less.
My Durango would run around 2100 to 2300 RPMS at 70 MPH----so slow down......and Good Luck.

You can get more performance, or better economy, but you are going to be hard put to get both.
Probably the best thing you can do, that will be the most bang for your buck is to do a "tuner" computer programming. You can get them (Hypertech, Super Chips) pretty much anywhere on line or at speed shops. They run ~ $450.00 and are legal in all states. SOME other additions are not.
Chemicals won't help all that much.
