Just curious if any of you are using this Aero Turbine muffler on your 3rd gen. I have a couple of freinds and co-workers in Oklahoma who are using them on a Powerstroke and Duramax. They sware by them mainly because of the milage increase but also claim a slight power improvement. They have documented 3-4 mpg increases with these things. If I could see this improvement I would definately be sold.

Any thoughts?

 

You will see some gains, I think 4 mpg is a little farfetched but if they are getting it right on. If you run mufflerless or you replaced stock muffler with High flo muffler an aeroturbine will help eliminate Drone.
