2" is 100% correct for HZ but I'll stick with the tailpipes on LH/HQ/HJ Holden V8 being somewhat smaller than 2" and likely 1 3/4" or 1 7/8" as I remember them looking really silly and thin.
As per previous post, HQ dual system tailpipes were 2". Single system tailpipes 1.75". LH dual system tailpipes 1 5/8".
