I suppose you could leave it off, but if it's going to be in Soviet service chances are the crew left the snorkel on(even if it was used very rarely.) It was an eight-hour procedure!.....so it's obvious they didn't use it often, nontheless they probably didn't go out of the way to ditch the snorkel either. 

Here's some pics of T-62 w/ snorkel attached to turret.....
