A 3D model of a DVR twin exhaust system with headers, originally proportioned to fit the Honda CRF450R 2021 dirtbike. The mesh can be adapted for other motorcycle models by adjusting or remodeling the headers and exhaust brackets. It is intended to add realistic detail to dirtbike and vehicle projects. Note that the included Blender file does not contain the original commercial textures used for carbon fiber and roughness due to licensing restrictions, so users will need to apply their own materials.
