Take a look at these mufflers... Aero-Turbine Mufflers
They are supposed to increase HP and MPG by extracting the exhaust gases through the muffler. The theory seems sound to me; it's the same Bernoulli effect that an airplane wing has.
I saw the "Two Guys Garage" episode that's mentioned in the website, and the dyno test did show a horsepower and torque increase.....
