Joke or not-joke? Intentional mod or just nature taking its course?
You'll often see it said around here that at low RPM where we tend to cruise for best MPG, an open exhaust may actually be working against you.

Metro - Thanks! No joke! This was an intentional mod to lose some weight and get some more power out of it. I wanted some
sound too. The stock muffler seemed restrictive. As far as I have been able to tell, there has not been any effect one way or another... though I do feel like torque is lacking below 1700 rpm.
The exhaust actually have the stock resonator on it.. so it is not completely mufflerless. I plan on adding a Jones Turbo-tube muffler and high-flow catalytic converter when I put on the 4-2-1 longtube header this spring. The pipe size is 1.875" all the way out to the back, which I have heard is almost too small for the motor
but those people are wanting more power, not FE.
