Near miss with SR22. Non local SR22 was sightseeing around ZZZ area with ADSB turned off.This non local SR22 was seen on initial arrival on ADS-B traffic on GLSP's (Glasair's) instruments. On another flight returning to airport GLSP made appropriate radio calls and observed no traffic on ADSB within 10 mile. 1;000 feet AGL turning downwind a very close miss with the same SR22 (verified by observation of subsequent landing). Situation observed too late to apply effective evasive maneuver.SR22 had turned off ADS-B instrumentation to avoid detection from low flight. During the observed portion of flight SR22 broke no altitude restrictions however turning off ADS-B broadcast compromised flight safety in this sparsely populated area.FAA should remind pilots that ADS-B is for safety not for enforcement; and is especially effective in avoiding midair collisions.
Pilot reported an NMAC with a Cirrus in the landing pattern.
