I have an 06 2500 quad 4x4 w/373 gears,has anybody removed the resonator.If so did it increase mileage any?

 

I have a 05 179,000 miles, replaced entire exhaust with a 5" system up to the turbo (took off the cat). I'm run stock except for a air cleaner. Gears are 4.10 and console says 20/21 mpg on the highway...

 

nothing but noise dude its straight through. the sides of it is packed with material that takes some sound out of it before the muffler. I;m not sure what that material is but the only thing it will do is louder and lighter it weighs 40 lbs or so maybe more. I have a MBRP 5inch with a muffler delete. exhaust noise is LOUD
