Sure it can be done, just finding some shop who will do it.

I had 2 of the 3 inch over the axle pipes from a chokemaster setup.
Had moved the panhard bar a little. Called around and nobody wanted to dick with it. So I went with a 4" Mufflex with a straight Magna. I like it so it's gonna stay.

As I remember from reading the sticky, a 4" pipe will support 657 hp without loss.
Though two 3" pipes surpass that as you have more flow area.
