As a 273-4bbl car, it would have the single rectangular cutout. As a Formula S car, it would have HD suspension, including uprated torsion bars and rear springs, anti-sway bar and 14 x 5.5 wheels.

Thanks for clarifying that. Would the exhaust pipe have had a rectangular tip to match the cutout or just a typical round end sloping downward?
