My VE R8 LS3 has mild cam, Di Filippo headers and 3" inch exhaust. Just wondering if there is a way I can modify it for a deeper sound? would swapping out the rear mufflers for hot dogs make a difference? Im happy with it at idle but not so happy with it when cruising around. Im chasing the deep burble, doesn't need to be any louder, just deeper if that makes sense?
