Funny how that works, eh? LOL!!!
As far as better MPG, there are the basics,,, Good air filter/tire pressure/engine in good running order, etc.
WARNING!!! DO NOT CONTINUE READING IF YOU HAVE A RAGING CASE OF "IGOTTAMOD!" THE INFO LISTED BELOW WILL BE HIGHLY DISCOURAGING!!!!
Changing the exhaust won't provide better MPG because a lifetime supply of 'Igottahearitroar' is included with each and every new system,,,,
#1 way to get better MPG??? SLOW DOWN!!!
Coast,,,, Rolling up to stoplights is far better than 'blast and brake'
When it turns green,,, ease off the line. I swear, it never fails,, the cars that blast off the line get multiple car lengths on me ASAP, but I end up catching back up with them in a 1/2 block so,,, who got where first?
Lift kits and jumbo-sized tires???? HA!!! That's just asking for a MPG 'hit'
CAI's??? Been there / done that. Lotsa 'Igottahearitroar' included, and quite frankly, if the engine can't use 7,500 CFM, there's no gain to be had from a system that will flow 7,500 CFM.
For MPG, you simply can't beat a modern
OEM intake system with a clean filter. As far as 'cold', the RAM already comes with a 100% 'cold' air system,,, Most aftermarket CAI's are not drawing 100% of their air from a cool source, so why they are sold as 'cold' air intakes,,, eh,, the world may never know,,,
Only use cruise on 'near flat' ground,,, If the vehicle has to downshift in cruise, chances are, you can do better by ditching cruise and properly using your momentum. Gain a little extra speed on the downhill then lose it (and then some) before cresting the next hill. (Don't do this to the extent of disrupting the flow of traffic, but 'riding the roller-coaster' will net you better mpg than powering up each and every hill in cruise)
Still with me?
Reduce weight. Don't carry 'everything and the kitchen sink' with you. With the exception of perhaps emergency equipment, get rid of everything you don't use on a regular basis. Plan ahead, don't just carry a buncha crap you 'might' need,,,,,,, someday,,,,,,,, maybe,,,,,,,, for 'whatever',,,,,,,,,,
Use the lowest octane fuel the manufacturer recommends for your specific vehicle. (For the RAM 5.7 its typically 89, with 87 'acceptable') There is no more 'energy' in a gallon of 93 than there is a gallon of 87. Octane is, in lay-mens terms, resistance
to ignition,,, Some low compression engines will actually carbon up if you run 93 through 'em, so don't 'assume' 'more is always better' when it come to octane. Octane needs to match the engines requirements. No more, no less.
As I spend a lot of time sitting in traffic/stop and go driving around Houston, I run 87. Out on the super-slab during trips, I'll opt for 89 at times.
Pretty sure I lost everyone by now,,, Yeah, I know,,, I'm just not any 'fun',, LOL!!!
