Here's a quick video comparing the Roush axle back to the Hushpower axle back on my car. I have a Lethal Off-Road X pipe too.
The Hushpower has more drone on my car, the Roush has some, but much less.
I like the sound of the Hushpowers better, so I put some Damplifier Pro in the trunk, and it tamed the drone.
The drone is still there, but it is livable now. I only put on 10 sheets in different spots in the trunk, I didn't cover everything. Didn't want to soundproof as much as stop the vibration to get rid of the drone.
I didn't ecpect it to work very well, but it worked surprisingly well.
I may add some more this srping, but for now I'm done.
I'm putting the Roushes up for sale. PM me if interested...
