New Exhaust is killing my MPG's!!

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!!

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

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.

i thought your suppose to stay on the throttle when a cop is behind you, that way he can't read your plate because of all the smoke
