A method of using an exhaust flow simulation system to test the effects of exhaust system conditions on various materials. The device includes a handle assembly having upper and lower handle portions which are detachable from one another. The resilient outer ring and the inner ring are compressed between the tire and the wheel hub under normal tire air pressure, and a space serving to increase driving comfortability and keep the outer ring from contacting the inner surface of the tire tread is designed between the resilient outer ring and the inner surface of the tire tread. Depending on the assigned categories and the characteristics of the paths, the data is mapped to one or more of the transmitter’s antennas to select a suitable transmission path. This may permit toggling the scan control signal during either a high phase or a low phase of the master clock, and may also enable testing the pulse functionality of each scan flop.
