XYBORX development - Day 7: Side cut

I'm cutting out a long lines of meshes to create void gap between the front fender and the hood chassis so that i could create ventilation duct for the engine and placement for new finned head lights which trails all the way to the top.  This long gash looks are uniquely for XYBORX, a new styling in car design.  I'm still trying to smoothen out the lines manually without using any Spline tools to control the curves....pure hand made.  Expected to have 6 exhaust port, 3x on each side infront of the door.
