A friend installed this gizmo in my truck two months ago. After 30 seconds first start I noticed that the engine became soooo quiet. At first I thought the RPM went down because of the water, but no, the device has definitely changed the way my engine works - it does not ping anymore!

Another thing I noticed right away was that the absolutely terrible stink previously coming out of my exhaust has gone down dramatically.
