Aliexpress vs Dominator DB killer Hard with Yamaha XT660r

Forgot to use 4k while recording. :/ Aliexpress vs Dominator DB killer Hard with Yamaha XT660r I found Dominator DB killer much better in sound. Aliexpress is more quiet. It is not that realistic test because wind might affect the DB reader. Measured from ~5 meters. MOT measures from ~15 meters. XT660r is measured at 84db from factory with its own original exhaust system(atleast that is printed on frame card). Recorded with: A6400 with Rode microphone.
