Ambient temperature was 25 degrees. The night before was around 20 degrees. At the begining i reved it up to 1600rpm. After the primer stoped up to 2500-3000. The car has 1400km at the moment. Im really not sure if this is actually supposed to be a sport exhaust or not. Atleast it makes more noise than my parents 330i on startup. Also the vibrating sound makes me think theres nothing inside the pipes to delibaretley quieten the sound. I love the sound.
