Shopping for mufflers online to replace my aging one, and hoping to find something lighter, thinner, and not noisy, I came across this one: Negative Supercharging Emission Vapouriser Muffler - Impulse Engine Technologies Pty Ltd - Australia

Perhaps it belongs in the unicorn corral, perhaps not, I don't know. Look at their emissions data. Given the recent discussion about CATs and cooling during EOC, this seems interesting. But I will not be getting one... it would not fit my car, I bet its costly, and well... I'm skeptical of the site's claims for FE and for some of the emissions benefits. What do you think?

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.
