A better question is do u have a reason to justify installing one? On a stock cube motor it's over kill, also is your intake ported to 58mm?
More info on your car plz
As in any industry .. Well known brand names cost more than comparably equal little known names.

The cheaper priced ones are cast aluminum and ugly while the more expensive ones are billet aluminum and look better plus billet isn't porous like cast.

IMO, the TPiS 58mm, although pricey, would be the one to go with.

I saw a dyno-result not too long ago (forget where) of a back-to-back comparison between a 52mm and a 58mm on the same motor and IIRC the gains were trivial.
