The so called cross over effect does't exist on an even fire engine.
If it did you can bet the factory would have used it and not bothered w/ vram and vcam.
It doesn't work on Ferrari V8s(even fire) or champ car V8s(also even fire)
It does work on odd fire American V8s w/ 90 degree blocks and 90 degree cranks because of the consecutive firing of cylinders on the same bank. It prevents the overload of the mufflers that would occur when properly sized for the rest of the cylinders.
For dual in and out you want the Flowmaster 80 series 2 chamber #42852 2x 2.5" In and 2x2.5" out.
Many prefer the cross flow Magnaflow mufflers
