Helmholtz Resonance exhaust
After reading this months Fact or Fiction topic on Helmholtz Resonance exhaust in Import Tuner , I'm pretty intrigued. After a little researching, it appears the technology is more often discussed with intake manifolds than anything, but is this the wheel reinvented?
The gist is this : "Exhaust gasses are blown across built in resonance chambers, and the frequency of pressure waves created therein pushes exhaust gas through the tubing and out into the atmosphere"

The science appears pretty solid, but to what power level does it remain effective and gains remain to be seen?
