Gas milleage

[etienne1982]

Hi everyone !

I'm new in this website, and I want to know how is the gas milleage from your car, and what mods you've made in this way...

Sorry for my english !

I have a 04 Aveo hatchback with 5-speed transmission.
My mods are :

-modular cold air intake (complete);
-NGK iridium spark plugs;
-Bosch spark plugs wires;
-Magnaflow XL Turbo muffler

and I cutted off the first muffler and the resonator. At idle speed, its sounds like a 6, but above 2500 rpm sounds like a Civic straight pipe....

My estimate for gas milleage is around 50 mpg for highway.
What about your car ?

Thanks

50 sounds a bit too high... I'd say 40 is the highest so far... for 50 you would have to drive really carefully. I know that after I did my intake/catback exhaust, I'm supposed to get better gas mileage, but it sounds so cool for the first few weeks of getting them - you rev it up every chance you get so your gas mileage goes down because of that. And about sounding like a straight civic - that's what I wanted to avoid so that's what I talked to the guy who welded my muffler about. They took both resonators out and put one back in (cherry bomb) and they put in a twister muffler (they're known for the lowest sound you can get out of 4 cylinder).

also, I would say that with anything that gives you HP and better gas mileage, you tend to go for HP...
