Just put a MBRP 4" turbo back on the ole truck and my gas mileage has gone to chit!

I like the way it sounds so much I find myself praying for red lights just so I can get on it again!! :D

Not to mention my girlfriend is mad at me because now I drive around with all the windows down so I can here it roar........

I don't think it's the exhaust that's hurting your mpg's I think it's the red lights. lol:D

It's worth it! Mine dropped too, b/c I went from shifling at 2000 to over 2500 just to hear it bellow.

Did you order it with the optional size 13 heavy foot covers?

You are suffering from Exhaust Syndrome.

You are so into the sound and power, that you keep flooring it. Try this: Drive like there is a cop behind you and you have warrants for your arrest. Watch how the exhaust helps you out at least 1 mpg at minimum.

I've learned on my Mustang, on my Mark VIII and a few others. Stay off it, be nice and watch the MPGs rise.
