Yes, but to a lessor extent: length is the primary factor.
The Corsa system uses cancellation techniques to eliminate much of the resonant frequency "drone" by (essentially).
Through the use of select lengths of closed tubes, the system capture the specific (drone) frequency sound waves and reflecting them back on themselves resulting in cancelling the particular frequency...and any frequencies close to the objective wave.
The Corsa system is divided into two sections; the resonator and the muffler - both having frequency resonator chambers of different lengths in order to broaden the range of cancellation (if you will).
