Not sure if anyone has heard this before... but this is a 5.0 with a tune on it that adjusts the variable valve timing to make the car sound like it has cams installed.
According to the other thread I read there is no performance gains, it just sounds mean as hell.
The car has an axle back system w/no cats.
