O-200 exhaust stacks

[couleeone]

I was looking at recent posted pictures of newcub's legend ( beautiful cub by the way!) and noticed there is only one exhaust stack but larger coming through the cowling whereas my sport cub has two separate stacks coming through the cowling but seem smaller than the legend.

Can anyone tell me why the difference?
