I have seen other, less thorough tests in which something called a "silencer" also fails to do the job a muffler does. Did you watch the video? I cannot recall readily this morning but I think he calls a few of these "silencers".... maybe not.

Also, there are "lollipops."

I imagine one could try to tune the spund with the shape and position of the baffle, but I am getting the impression that the only really effective silencer is actually called a muffler. Lol.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
