Personally I won't consider a new Mustang without it. Honestly I even want it when looking at a used Mustang. Now granted I have only used it on a GT so I can't speak for the differences on the Eco, but on the GT it is very cool. You can tell a difference in all the modes and I think the track setting gives enough that a aftermarket exhaust no longer needs to be the first mod.

(I have owned a few non Mustang cars over the years as well, but always try to have a Mustang with it or come quickly back to a Mustang!)
