If you're not interested in the topic, move on. Don't let my topic be the reason you don't have something productive be the reason you respond.
I mean, you can still hear the 'swoosh' sound with the stock setup (however, I will admit, it's usually very difficult to hear). Has to be in a quietish-area so it isn't washed out by other noises (works better if it's somewhere enclosed such as parking garage instead of out in the open). Windows down obviously if you're in the car and want to hear it. Then you have to get to mid-high RPMs and abruptly take your foot off the gas and you'll hear the PSHHH sound.
Try decaf. Most people recognize a little humor when they see it. Besides, my opinion on spending money on something with little reward or gain is just that. My opinion. Where was this outrage for the one who posted the humorous YouTube video? But hey, for those that like swoosh, go for it!

Well it makes a sound as intended so it does do that. As far as voiding the warranty you'd need to have a pretty low IQ to fall for that dealer BS.
