what is the difference between an E cover vs an S cover

[derick's gn]

i see these terms alot here but what is the difference?
does it matter for a strictly driven street car?
or is it only on the larger size turbos?
i did not see it in any of the sticky's.

Hartlines have a new post for turbos in the specials section and it tells the inlet and outlet sizes for the E, S, and H covers
