No you don't lose the six disc changer. It is still there, behind the screen, as well as the +1 disc for the navigation. so a total of seven disc holder. Only thing you lose is, if you have the shaker 1000, you dont have hook ups for the rear subs in the trunk.
Stock for now. Two GT take off muffler, connected to a GT H-pipe.Upgrade instrument cluster. Shorty antenna. GT rear bumper. GT side skirts. GT front and rear sway bars. So many GT parts, and still a V6 engine. Damn. 18 inch Deep Dish Black rims, with polish lip. 255 front, 275 rear, soon changed to 285.
