Yes, the Rattle sound is completely gone for me.
The vibration is still there.... but it's more of a powerful grumble. The thing now has a growl along with a snarl with the addition of the IC, Downpipes, ZFG tune and Borla S-Type's.
Pushing 500+HP, I want to feel that grumble in truck. If I wanted quiet along with insane speed I would have went with the Tesla Model S!
