I guess you would call them a "mid'length". Longer than a shorty but much shorter than a long tube.

For my application they are probably as good as it would get. A couple spark plugs are a bear to get in and the rear passenger side bolt can only be accessed from under the car. A skinny 5/16s box end can tighten the rest of the bolts down okay.
