Sound Generator Disable

You must be driving with a relentless heavy foot all the time to hear the sound generator that often.

First, I would say that I don't think the factory setup is a fake sound. It's just letting the actual sound from the engine's intake be heard, still, people may not like it.
There are a few ways to get rid of the sound generator.
Cheapest: Just us a cap.
Use the cheap resonator from the RX350 (17893-31170 or 0P150).
Use the 2GR intake pipe without the sound generator (17881-31350).
To each their own, I like the sound, but if you want it to be quieter, I can see getting rid of it.

Yep, I totally agree. It would be almost impossible for me to put the sound generator back on, now that I am used to the lack of noise. You now hear the engine RPM, transmission whirring and even the exhaust note. I totally realize this is just my opinion, but it's much MUCH better. Now there's no "big production" (regarding the noise level) when you get on the gas heavy, just smooth acceleration with some mild associated noises. Now when I "get on the gas" my passenger(s) know it because of the feeling of acceleration...not because of the noise they hear. The PERCEPTION is that the car seems faster - Lord knows it is NOT so save your comments, LOL!
I’ve been driving like a grandpa, breaking in my 2018 and trying to maximize MPGs. Now that it’s been more than a month, I’ve been goosing the pedal a little more and I’ve found the drone to be a little out of place... not enjoying the sound, but I can get used to it.
For $10 I’m certainly going to order the RX cap and see how that works...
Thanks!
could it be the cold weather and how that impacts intake, mapping etc.? I don’t drive around with my hair on fire, but the difference is substantial. I kinda wish it was even quieter at full throttle those times when I do need it. Not a huge fan of the V6 note. Now my 2GS’ V8 note...just starting that car sounded cool.
I stepped on it from the on ramp while getting on to the highway a couple days ago and I didn't hear the expected engine acceleration, so much so that I pressed the pedal even harder and hit the WOT/kick down mode. Then I remembered that it's not supposed to be as loud with the sound generator gone... I guess I've not fully adjusted yet, and I'm still subconsciously expecting the past sensory inputs that have always been there, so I have to say that the cabin is definitely quieter, and I like it!
If you remove the sound generator it gets louder. Damnit it is louder now.
Here are a couple short videos with the sound generator removed. There's a full-throttle pull towards the end of the first vid.
I'm not sure how helpful this will be since this is an older video I've had and it was recorded with a different cam/mic but hopefully this gives you a feel for the difference in sound at least (though the first two videos are recorded with much better audio quality but I tried haha)

The proof is in the pudding as they say. The wife used to get all bent out of shape if that bark-box made any noise, thinking I’m hammering around. It was just a sound that would quickly annoy her. With bark-box removed, even in sport mode the car is pulling way harder than it was before and she continues texting away on her phone, looking around, whatever...unless I truly hammer it, she won’t even looked up! Serenity in more ways than one! 8D

He means in relation to the noise. Whereas with the sound generator, a little bit of acceleration = a lot of noise which alerts the passengers in the car to the driver's intentions to speed up. Without the noise generator, a little bit of acceleration ≠ a lot of noise (the sound is more muted) which means you're a little bit more incognito with your acceleration before the engine sound gives it away.

Removing the sound generator makes absolutely zero (e.g. ZILCH) difference in performance.

I think it's safe to say that what he meant was - he could 'get on it' harder (use more throttle) than before when he had the sound generator and his wife is now not bothered like she had been before even when using less throttle.

Gotcha

That’s correct

Removing the Sound Generator is fine. In fact many Lexus FSport intakes use a pipe that removes the sound generator. I would probably recommend a good aftermarket intake tho.
