thinking of keeping the same design but adding an xpipe after the front resonators and deleting the rear resonators at the same time competition mufflers at the end with open valves..on a 650i gc what are your thoughts?

unless you are doing major mods that make the exhaust a point of restriction (i.e. big turbos, free flowing intake, catless downpipes, and a a full tune to control everything and turn up the boost), it wont make a bit of difference other than noise.

Pretty much just to enhance the sound of the exhaust system

"Enhance" is a very subjective term. with one off systems like that, no one will have any idea what it will sound like until you do it.
