Yea it's a drone but loud only the first few gears especially at lower RPMs between 1000-1800k. And worse when speeding up with foot barely mashing gas pedal I get a sound that rumbles inside cabin so much and is too loud in the rear seats. Wonder if it would help decrease cabin noise level if I returned both valves to stock position and dynomat under rear seat and upper trunk lid portion inside of trunk.
