Motor sound throughout rev
I remember reading about this in another thread, but I can't find the exact thread. I've noticed that I hear that mean engine sound up until about 4500 to 5000rpm. You would think it would continue to get louder all the way to redline, and really get loud. Yet I hear more of the engine whine than a growl. Does that make sense, or are my ears messing with me? I'm pretty sure this will change once I put exhaust and intake on the car. I'm planning on this later on, but that Meisterschaft exhaust isn't cheap! But that sound you hear early on from the car, is just epic! I just want more of it and louder!
Cheers mates,

buy the Borla for a fraction of the price you and won't be disappointed. I don't even hear that "engine sound" anymore after the Borla is installed. Now the F growls from idle to redline

No way!! Are you serious!?!? That's crazy! I had no idea. I thought they were taking the sound from the engine cabin, and playing it through a speaker through the glovebox. I had no idea it was completely computer generated. I heard the M4's are the same?
I will definitely take a look at the Borla exhaust. The only reason I really liked the Meisterschaft, was I could close the valves. So when I leave late at night for work, I don't wake up the entire neighborhood. Thanks ssmoked!!

No, it is not fake unlike the BMW. It is well documented. The augmented noise you hear are actually engine noises amplified through the speakers. Some of the harsh frequencies are cancelled out while the good noises are amplified.

Actually it might not be fake at all, I'm not 100% sure on this but I remember reading something about it somewhere... there is a flap on the intake that opens and closes when the engine reaches certain RPMs producing a more aggressive and awesome sound which in turn goes through the mic and into the cabin, amplified through the speaker. Now I'd have to take a look at it, but I think depending on what mode (normal, sport, etc) the flap will function or not... anybody can confirm this?

Pop the the hood and rev the engine, it doesn't sound anything like what you hear in the cabin. When the computer/speaker tune out static noise and amplify noise into perfection, isn't that considered fake?

the flap opens in all modes besides eco. When it's in sport+ it's considerably louder than normal and sport mode.

From Lexus press material:
The sound blasting from the RC F’s quad stacked tailpipes is sure to turn heads and raise pulse rates. Yet, Lexus also had to design the cabin to be quiet enough to enable enjoyment of the standard premium sound system or sonically stunning Mark Levinson® Premium Surround Sound system.
How could RC F drivers enjoy both? The answer is Active Sound Control (ASC), which lets the driver control enhanced exhaust, intake and mechanical sounds within the cabin. Specifically, Lexus sought to approximate the aural experience provided by the Lexus LFA, which issued some of the most stirring mechanical intake and exhaust notes of any supercar. Although LFA V10 engine revs to 9,000 rpm and RC F’s V8 to 7,100 rpm, the engineers have come close.
An electronic control unit mounted beneath the instrument panel takes input from engine sounds, including varying engine speed, vehicle speed and throttle position and generates augmented sound through an actuator. It is entirely separate from audio system, so there’s no reduction in music fidelity.
Most importantly is the driver controls ASC. It’s activated only in SPORT S+ mode, not Eco, Normal and SPORT S modes. And when it’s on, ASC blends with the natural intake and exhaust sounds to about a 50:50 ratio.
At engine speeds up to 3,000 rpm, ASC issues a steady tone of low and deep sounds.
As revs rise, the tone transforms into a higher-pitched note that blends with the engine’s mechanical sounds, culminating in a free-soaring sound beyond 6,000 rpm.

Tons of video on YouTube recording from the outside has the induction sound under load and acceleration.

My whole point is that the sound in the cabin is not all natural and computer speaker generated, as confirmed by the press release by Lexus. Going technical, all natural sound is only generated by engine rev, intake and exhaust (think lambo and such).
Regarding driving next to a barrier and hearing your exhaust from reflected noise is comical. Strap a GoPro next to a Honda Civic muffler and you would hear some noise too under full throttle. That's the main reason why many Rcf owners choose to add after market exhaust simply because the stocks are too quiet. Btw my Borla is great.
What you hear in cabin from the ASC is enhanced noise and is completely different from what a pedestrian would hear on the street.

Believe what you will. Just making the point that it's not fake.

We got to test out a couple RC-Fs stock vs ARK exhaust and aftermarket intake. The ASC is nice and all, but it really does not compare to an aftermarket exhaust and intake. With an aftermarket exhaust and intake you can hear it in any mode, not just Sport + of course, and you can really hear the V8 above 4,000 rpm all the way to redline!
