So there's no confusion this is what we're referring to:
1. First go to Appearance > Menus and click 'Screen Options' at the top.
2. Tick the 'CSS Classes' checkbox
3. Add a menu item and click the little down arrow within it to reveal the CSS Classes input box.
To be similar to Get a Quote add this to CSS Classes:
right secondary arrow no-divider
To be similar to Downloads add this to CSS Classes:
right secondary download
This will align the menu to the right and add the little icon next to it. If you don't want to use the icon leave out arrow or download from your CSS Classes.
The lighter grey is controlled in Theme Options > Colors > 'Navigation Background Secondary Color'
