Straight pipe fuel mileage

Before i replaced my muffler and kitty with straightpipe i was averaging around 18.8 or MPG on the interstate. Now after adding the straight pipe, i cant break 16.5 MPG on the interstate. I know the lie a meter isnt always accurant but either way i've still lost 2 MPG, WHY ??????

You have to do the math. Don't bother with the meter.

Yea, hand calculate it.
It would give better mpg but ever snce I got my exhaust my avg mpg dropped because I enjoy the noise.
But the ONLY reason I got my delete pipes was to drop EGT's and could not be happier for how they perform.

More than likely you are enjoying the sound laying into it more. Should make zero difference in MPG.

correct and actually if you listen to companies like MBRP they say it improves REGULAR mpg by 1-2.

I've heard people say that exhaust without tuning will drop your mpg
