Disclosed area coating-free metallic thermoplastic resin composition having improved metallic texture and gloss and a molded product having extrusion-molded the same. For example, the molded produce may be manufactured by feeding a master batch containing a styrene-acrylonitrile (SAN) resin and a metal in a weather resistant thermoplastic resin containing an acrylonitrile styrene acrylate (ASA) resin in a side feeding method. The coating-free metallic thermoplastic resin composition may be optimized in types and contents of the master batch and dispersant contained therein. The molded product may be manufactured by feeding the master batch in the side feeding method to improve various physical properties, increase the dispensability and compatibility between compositions, and improve black streaks and flow marks, thereby improving metallic texture and gloss as well as suppressing the occurrence of the appearance defects.
