The Stormers reached the Heineken Champions Cup quarter-finals for the first time despite three late Harlequins tries in Cape Town.
In a blistering start, the hosts' Deon Fourie and Alex Dombrandt of Quins exchanged tries before Steven Kitshoff re-established Stormers' lead.
Fourie doubled his tally before Damian Willemse's finish and a Willie Engelbrecht score added the gloss.
Dombrandt, Andre Esterhuizen and Joe Marchant scored late consolations.
Stormers will visit either Exeter or Montpellier in the last eight.
