Anyone have the flow masters axleback? does it improve gas mileage?

 

The only thing an axle-back will really change is sound.

The key to better fuel economy is your right foot.

 

I have the flowamster. make good powers.

 

 

I recently installed a set of Flowmaster Outlaws. I have never checked my gas mileage, dont care. They sound fantastic but i will warn you that on my car at least, they have a very pronounced drone at 2k RPM in 6th gear.
