scheerspeed: can you elaborate more on the resonator mod for retaining backpressure?

here is my interpretation:

The OEM pipe from the engine to the resonator is diamerter X and the pipe exiting the resonator is diameter X-Y, where Y is a small value. In addition, the pipe exiting the resonator extended into the resonator device about 2 inches. So the reduction in pipe diameter (from inlet to outlet) and maybe shortening of the exhast path within the resonator makes up for the backpressure of the OEM exhaust effect.

Anyone with engineering support?
