The rear exhaust flap located in the muffler will not affect anything in the car. It’s commonly referred to as a “golf tee mod” to actually disable it without removing the muffler. I am going to try to upload my first video of it revving, although it’s not terribly great. I might see if I can get another video later today maybe.
