Quick answer, calms down (does not stop) the popping from the exhaust after you change the exhaust.
If you are not going to change the exhaust (I am betting you will
), do not do it, yes even with the stock exhaust the popping is there but not noticeable, the reid valve allows fresh air into the exhaust port to allow unburned fuel (on deceleration) to ignite in the pipe thus causing a sound most describe as a pop, I call it backfire, very noticeable on muscle cars with straight pipes.
Word of caution, you will not believe the sound volume from the BAK, the first time I started it I thought I had done something wrong, actually I had done something right, put on a BAK, sweet look and sounds good now.
