I haven't read the thread, have no idea if I'm the only one who hated switching off the tube. I think it is very ridiculous to do that.
My car is a 2018 BRZ AT. I hear some different kinds of sounds while driving. Some are not very pleasant, like a timing belt is struggling, and some other noises that I got used to hearing from "normal" cars such as a Corolla or Renault family car. However I also hear some good ones as well. Especially between 4000-5500 rpm there is a resonance like sound. I thought it was coming from the exhaust until I've done the switching-off thing. I remember I've read some comments people say something like "intake voice is stupid, and should be deleted for sure." So I was expecting to remove the unpleasant noises.
I couldn't hear a difference until ~3800 rpm when I do the switching-off; however after 4000 rpm, all the sound that I like is gone. What is left is what is I dislike to hear. I wasn't expecting a big difference. However the difference after 4000 rpm is like black/white. I like exaggerating things, but this is not one.
Maybe there is a problem on my ears that I cannot hear the frequencies that those who liked this mod can. But I literally felt like I'm driving a Corolla without the so-called stupid intake sound.
While making this tries, I've came across a great car. This one exactly:
I've followed it for a while, and I guess the driver understood how I liked his car, and showed me some of its capabilities, and it's great sound. I once drove that car and it was mind blowing.
I bought a BRZ, because I like a Ferrari more than a Corolla. If I wanted a silent car, and listen to its stupid engine's struggling sound, I would stay on my old Renault Clio!
