So i just put a 7.5" fabtech suspension lift with 35" tires on my '02 f150, but am afraid of how much more money im going to be spending on gas. What is the best intake/ exhaust system that is goin to give me the best mileage so im not going broke paying for these rediculous gas prices...

 

If you are worried about gas, I doubt if any intake/exhaust combo will even come close to paying for itself, unless you have the truck for 15 years or so. It will give you more horsepower (less MPG )

 

My frist mod was a Borla cat-back SISO and I gained 1.8 mpg highway.. no idea if it would help much with the lift and wheels you're using tho.. that's one huge brick to push through the air!

 

Man you coulda bought a lot of gas for the cost of the lift and tires
Run it like it's been beaten and enjoy it.....

 

I have an intake, exhaust, and tuner on truck. The only thing that helped the mileage was the tuner, and that gets me about 1mpg better running 93 octane on the performance setting. But then again I didn't buy any of them for increased mileage either. If you think that by putting on exhaust and intake on you are going to get your mileage back, you are just kidding yourself. You will get some extra power and a louder meaner sounding truck, but most people will not see much of/any improvement in mileage.

Honestly if you want to get better mileage put the truck back to stock, otherwise you gotta pay if you want to play.
