I've not been back in the forum for awhile and I'm surprised to find that several people don't find the difference after swapping the sound generator with the quiet cap.
It was a big difference for me. Mind you, the big difference in engine sound occurs at acceleration from stop and also when running at low speed (i.e. rush hour traffic).
With the sound resonator, there was a rumble noise when accelerating from stop, or running at constant low speed; after capping it off, I don't hear the rumble at all and the engine is much quieter. Now it feels more like a quiet luxury car, which is what a Lexus ride should be.
Sorry to hear people complaining about wasting money. It was the best 16 bucks I ever spent on my car.

I takes 20 minutes or less to swap it out. I have no regrets doing mine.
You unlatch the engine filter housing top, loosen the clamp holding the generator and remove and install the plug and tighten everything up and done.
This is for the 350. The 450 maybe different.

I bought the RX F-Sport 5 months ago because I just love the look of the grille.
Immediately after I got it I noticed the harsh engine noise during acceleration (not even hard acceleration, just normal driving), I was quite disappointed with it because I expect to have a much more quiet ride from a Lexus, I later found out that the F-Sport engine is equipped with a "sound generator" that cannot be disabled.
So after months of searching, I found an online (Cdn) store selling Lexus parts that has a "cap" for the non-Fsport engine.
I bought it a few weeks ago, replaced the "sound generator" with this "cap" and voila ... a quiet RX F-sport. The engine is much more quiet now and I can totally enjoy the ride in my RX.
The "cap" only cost me CDN$16 while the "sound generator" was selling for $113 (for those who wants to get extra engine noise)
If anyone interested, let me know and I'll post some pictures.
I know there are fans of the "sound generator" out there, I understand why you like to hear the excessive noise which is your preference, I just prefer the quiet ride so no need to ask me why.
