I pretty much have that setup and the milage has been the same from the beginning. Last time I checked my scangauge I'm getting 32 mpg average which is perfect. Even when I installed the 18" there was no change.

Now remember that it's going to sound nice so, no lead foot ok!

all the aftermarket parts is just letting the car breath easier, so it should save gas. but i think a CAI would save an extra mile more then a short ram intake since short rams sucks hot air.

also keeping your oil every 3k-5k miles will get the most out of MPG . thinner oil does savee gas too

i am thinking about getting a Megan Racing Drift Spec exhaust...and wud thier me any changes of even losing 1 mile to a gallon??

It's probably more or less the intake? The aftermarket one is more efficient. And whatever doesn't affect A/F ratios significantly like an f/i setup won't change your gas mileage.

And for chrissake, NO an exhaust will not affect your gas mileage. Think about this...the exhaust just manages the hot gasses exiting your engine? How should that affect gas milage when the engine is the responsible for what mileage you're getting?

The short ram I have is enclosed in an aluminum shroud which has a gasket that seal on the hood when shut and pulls air from the fender area....but I get what your saying

when you go over like 20mph all the air is sucked from out under the engine bay. plus when the sun is out is makes the ground very hot soo with a CAI you are just sucking hot air anyways.

Now that i have complete exhaust, Ingen CAI -> Weapon R 4-2-1 -> Spipe -> Custom mid -> Tanabe G.

I can attest that i get better gas mileage on the highways, i just drove 450 miles on 13.9 gallons of gas, that makes 32.37 MPG with about 400 of that strictly on the highways at 75-80 mph.
