the pipe itself is not "round", its a simple combination of two cilinders with a flat base. it may look round in the reference but thats because its in another perspective.
the shading on that 3D model, the shading on the SMW pipe and the shading you are using in your sprite also are the same, and thats wrong since those are three completely diferent light sources. while your sprites are suposed to have a a light source on the top right corner, the light source on the 3D model come from the viewer, and the SMW pipe doesn't really sport a light source(its a rather functional shading to remark its cilindrical shape).
my edit is far from perfect, but it should give you an idea on how the light should affect the shapes in the kart.(and other issues related on the kart's shape and scale)
