Whining noise during hard acceleration

so i finally passed 1k mile and am pushing the car harder now. I noticed from a stop or slow roll under hard acceleration, other than the nice exhaust burp sound, i also hear a faint whining noise around 4k-6k rpm. The noise also gets louder as the rpm gets higher. this doesn't happen under higher speed down shift so it's usually only at 1st and 2nd gear. i watched a lot of youtube videos and can kind of hear the same sound. any of you hear this on your gla45 too? thanks guys.
