  1. I have the Dynomax VT. It is a straight through design but incorporates a spring loaded valve that stays mostly closed under light loads. No drone whatsoever and the noise level is not bad just driving around. Under load though the valve opens up for unrestricted flow. I dont see them on Dynomax's website now.
    I think they’re not making the VT’s anymore
Sure wish I could hear sound clip of the oem style walkers with hci and off road h pipe.
Also flow numbers.
