It is not flat like that for performance.  Just the way the factory builds them.  Not sure any body makes an round cross under that works with factory head pipe, and brackets.  Doubt a round one would be any gains with still having the stock motor and headpipe.

Fullsac when you use his head pipe it comes with a round cross under and brackets.
