I installed a newly delivered VCMuzzler II on our '13 EX-L today and took it for a spin. As advertised VCM is kaput and temp gauge runs a click lower on the gauge with the blue resistor. The cruise vibration is pretty much gone but at about 25-35 mph-ish a fine vibration seems evident. What are the odds that this is my imagination vs something else...like the prop shaft? The tires are brand new and were balanced with a roadforce machine.
