Magnaflow Surprise!

[20Ram4X]

Installed a bolt in Magnaflow can yesterday. The installation went smooth, but I wasn't really sold on the added noise. I thought maybe I'd get used to it. Today I did a 100 mile round trip drive to visit the in-laws and my avg mpg went from 14.5 to 17.5! Sounds great now...

so just changing the muffler for you 3mpg more? I thought most folks lost mpg with exhaust mods.

Makes sense You drove slower cause the noise was loud af?

Similar to my thought. Maybe he didn't have to run it hard just to hear it like you do with the factory exhaust.

I’d like a more free flowing muffler without it being too loud.

The theory behind it is that if you free up the exhaust flow, the throttle angle is less at a given speed. This may be bro science but my lifetime average of 14.5mpg is slowly creeping up and that's a mix of city/hwy driving. Stoked to put a few more miles on it and see what it does. The Magnaflow sound is pretty mellow although the cold start is a big aggressive.

3 MPG? I’ve never got better MPG from any of my countless exhaust mods as my foot is further on the pedal to enjoy blissful sounds.
