As it happens, most of the Mosquito night bombers didn't. You see flame gear on the very early Oboe markers, but by late 43 all the night Mossie bombers seem to have stub exhausts, including the low-level markers of 627 Sqn. The night fighters retained the dampeners, apparently the extra light interfered with aiming, and the intruder craft didn't want the ack gunners to have a clear target while they stooged around LW fields.
