What are you exactly trying to do?
Making a paintable exhaust?
Did you export the mesh by yourself?
If yes, did you apply a material with a texture before exporting?
Did you UVW map the mesh?
If not, you wont be able to change its color unless it was textured(most exhausts arent textured, tyey use a plane diffuse color and a reflection map), then you simply have to replace the texture.
