For realtime game asset, is it okay to delete backface polygon?

so i have an armor that has some gap from the body, so i need it to be separate. The question is can I delete the backface polygon to save some polygon?

If you never see the backfacing polygons, there is no reason to keep them. Waste of poly budget and texture space.

so its okay then? is it important to have some polygon going inside the back part? does that help with baking problem?

some engines need backfaces to cast shadows... 
and most of them does not draw faces they dont see from the cam...

i would ask the TDs...
