Best bang for the buck$$$
what is best mods for save MPG with my 5.7 HEMI ?
cold air intake
But then again you will be in the gas more to hear the new sound and feel the new power.
Programmer first! Biggest gain for the money, but all three together is best
for exhaust have you ever compared different option? What gives the best return for money
the original OEM single line with a good muffler and remove the resonator.
the double line OEM as the sport model with a good muffler.
real double line with a two catalytic converter with a good muffler.
when i worked in a dyno shop different engines react differently to each style. to say which exhaust option works best would be rather expensive. but best for the money would be in order
with that said yes a programmer isnt an option right now.but with the exhaust a full exhaust headers back is the best but really expensive with minor results. so a simple muffler swap would work best. saves wieght and frees up exhaust pressure. but you must be careful to much flow will yield negative results. unless built for it most motors require a certain amount of back pressure.
intakes also provide different results.there are 3 types stock,short air, and cold air. they all do different things.
thank you for your information it is very useful myself
no problem it is what i do. been building engines along time.
I've just got the programmer and muffler w/o cats now. Next is going to be LT headers and off-road Y. I'm thinking about ditching the spare tire to remove some weight, and make the truck a tad lighter=more mpg.
