Beautiful design and fabrication, almost, no, it is a work of art. I like the exhaust tip treatment. From. My past aero / hydro work I question the steep gradient on the outer channels. Did your CFD model inflow interference around tires and what turbulence model did you use, this is the current failure of CFD programs, prediction of separation point over a curved surface. You may want to use flow dye or yarns to determine real world flow separation.
