I think it's a litte more complex than that... Typically those chambers are called Helmholtz resonators. They are used to dampen resonances
but usually used in intakes. There is one on the Z in the drivers side intake accordion. You'll see them on many cars in various shapes, tuned to cancel out natural frequencies. I think it would take some smart acoustical engineer to come up with something for the exhaust that would work on your system..
