Have had my RC-F for a week now, and while I am so far loving the car, I'm not a fan of ACS. I searched around through various menus looking for a way to turn it off but no such luck. My dislike is because it's not real - sounds artificial. The car seems deceptively quick to me so far, I have to really get my foot into it but when I do it responds - but the ACS sort of makes it seem like it's doing more than it really is. My take on the ACS is that it is not a replacement for a throatier exhaust, which I think is what the car needs and what I'll be looking for as the first major mod.

Other opinions / recommended exhaust systems?

 

Have you found the fuse or unplugged the speaker yet ???

Does the stock exhaust have valves?


Lexus RC F to employ "ASC" - Active Sound Control for Interior Cabin..!!

Blame the customer for that. People want a quieter car and Lexus develops silky smooth engines and incorporates sound deadening materials throughout. Then they complain they want a louder more visceral experience so Lexus develops ASC. Now people are complaining about that.

An aftermarket exhaust should be the solution. But keep in mind its a GT car. If you want a visceral auditory experience you need to look at the coyote V8 in the mustang. But I wouldn't go near one.

 

Your point is well taken. This is my first Lexus, and I appreciate the sound deadening effort. I'm really just saying that an option to turn off ASC would have been good.

 

Yeah no thanks on the Mustang. I'm less of a fan of those than ASC by far. I think a good aftermarket exhaust will make all the difference.

 

I agree that the aftermarket exhaust system makes a huge difference, but the ASC is only active when it is in Sport + mode, so if you don't like the sound of it, just drive it on the other modes or upgrade to a aftermarket exhaust system like I did.

 

What exhaust are you running?

 

GTHaus Meisterschaft GTC exhaust system, I just updated my build thread with new exhaust videos if you want to check them out.

 

Can someone post how to remove that fuse? Also will it cause any other issues like a CEL?

 

I had no idea about this and have to say this is pretty lame to have fake engine noise. C/mon Lexus. What the heck are you thinking?

 

Lol! I Couldn't Believe it when i'd heard this on here, i mean REALLY! I haven't had anybody ask me about this when they've rode in the car & i'm Sure NOT going to Bring it Up if they Don't!

 

Exactly, anybody have info on this? So even if I go aftermarket exhaust then there is still the issue of ASC on top of that, which probably would really sound lame.

 

90% of the foods Americans buy is processed. Chemically altered with additives, "natural flavorings", etc. I don't see why ANC is any lamer than the fast food burger the average joe has for lunch.

 

Yep, but THIS makes the Burgers taste Better! i Don't think the Fake Engine Noise IMPROVES the Sound of the RCF!

 

Agree, it sounds like it's doing more than it is really doing. I see in the owner's manual that on the 350 it is possible to turn it off. I can't figure out why Lexus didn't put that option in the F
