With my 3" turboback and HF cat I can now get 280+ miles out of a tank of gas. Mostly highway 80mph but that's with some fun city mixed in. I am very happy.

 

how many miles per gallon is that?

so better airflow then better gass mileage huh?

 

After I installed my WORKS Exhale (muffler delete pipe), I noticed slightly better gas mileage also.

 

I went from 17-18 mpg, too 20+ mpg after drop-in filter, downpipe, and catback. thats in the city shifting at or before 3000 rpms.

 

I wonder why manufacturers don't have a similar setup as stock. They could advertise better gas mileage.

 

Becuase then they would have to worry more about emmisions, as most of these set ups won't pass Cali and other strictly regulated states. But yes, whenever the airflow is increased, the mileage always increases (this goes for any car).

 

roughly 285 miles on 12 gallons is roughly 24 mpg.

 

That would drive me crazy. I didn't buy the car to shift it BEFORE the turbo kicks in.

I get about 18-19mpg with a mix of spirited and normal driving. I didn't notice any mpg change with an exhaust.

 

If I could lighten up my right foot, I would get better gas mileage.......

*edit*
I normally get about 190-200 miles per tank. City Driving. Oh and the gas is 2.22 a gallon

 

Two tickets later I came to the realization that I had to choose carefully when to let the car loose. Plus gas prices are skyrocketing. Do you have a turbo back or cat-back exhaust?
