BMW M5 E39 | Dinan Headers | SS Race Cats | SS X-Pipe | Dinan Mufflers - Exhaust Sound Test

1st sound test is with automatic microphone and the sound is overblown.
2nd sound test is with manual microphone gain, turned way down.

If you wanna hear actually how loud the car is in real life.
To calibrate sound volume correct (to correct microphone gain), listen to manual gain sound level at 30 seconds forward, and increase your speaker/headphone volume so the conversation is clearly audible. Then when the car revs, you will truly hear how loud it is.
