No mpg gain, but a good sound.

Or a note in general LOL.

I can't wait to install my Magnaflow single in/dual out side exhaust (PN#16616). I have heard minivans with a better exhaust note than my truck!

But no, you won't really see an increase in MPGs. Most likely your mileage will go down because you can't keep your foot out of it!

Yes the exhaust tone was better but IMHO I think you loose low end torgue with after market exhaust.
