Now, at a high level, the secret sauce of a resonator design is the housing of the resonator (length/diameter), and how many diverging paths are implemented. I am not sure if there are resonators that affect only certain (unwanted) frequencies…but that would mean to identify which frequenc...
As exhaust gases exit the 328i/428i engine and flow into an AWE Tuning 180 Technology™ equipped resonator, they pass through strategically located ports, and into reflection chambers. Sound waves, carried by these exhaust gasses, bounce off the walls of the reflection chambers. By controlling ...
In the exhaust system, various elements, such as the manifold, catalyst, resonator, and muffler, are connected to the exhaust pipe. During the tuning of the exhaust system, the outer diameter of the pipe is increased, or its geometry is changed naturally, while each element is modified accord...
