Anyone on here have any experience with tuned exhausts on a lycoming, I am reading about a company Power Flow Systems that are going for approval for a muffler for my model of plane
Power Flow Systems, Inc - Tuned Airplane Exhaust Systems - Products

Some of the claimed performance benefits are pretty impressive, any thoughts anyone?
Edit: And just how the hell do you " tune" a muffler pipe ?
