Gas Milage? MagnaFlow exhaust Honda Civic 2006 ex
I just installed a Magnaflow catback exhaust to my Honda Civic ex 2006 auto, and now I'm dissapointed because my mpg was 30-35 a gallon average, and now my gas is 15-18 mpg. I've driven my car like 30 miles and I'm hoping to see mpg improvement. Does anyone know if my mpg will increase?

^ definitely not...
eric: how are you measuring your MPG? is it just a guess? i highly HIGHLY HIGHLY doubt your gas mileage decreased. the only reason that it might have by a little is that you didn't connect the IAT sensor on the intake (or some other sensor) and the car is running in limp mode.

It wouldn't change by that much.

You can't really gage your gas mileage based on a tiny portion of the tank. Run a whole tank (at least most of one) and the number will be higher. There are factors involved beyond your control, such as the extra weight of the gas.
