It also produces a sharper, harder edged tone that suits the S68 far better than the heavily silenced factory system.\u003c\/p\u003e\n\u003cp\u003eAn independent Varex valve system, controlled by remote, gives complete authority over the volume.

Sealed when closed for quiet running, and fully unobstructed when open for maximum flow and volume.
