I just did this the other day and it’s sounds glorious at all RPM’s now. Also it removes the small delay in throttle when accelerating from a stop. I’m not sure if it’s because of reduced back pressure or something else but it’s smoother and more immediate.
That's cool. Thx. Saw a gut a few weeks ago wire a remotely control box inline with the module in the trunk so the valves could be opened and closed remotely from in the car.
Just did the his on my LC and wow what’s difference. I did end disabling via trunk as I wasn’t comfortable leaving wires hanging . Either way worth it for sure.
So my 2021 vert only had one valve per side. I zipped tied and put painters tape over the male and female connectors to keep them clean. Does sound better at low rpm’s.
Mine is unplugped. But here is the thing, when it first starts, it sounds so good then after for about 2 seconds, you can hear the valve being closed which came back to the original state ( plugged ). Mine is 21 vertible.
I did unplug 2 connectors on my 2023 convertible while the car was off. When it starts it sounds awesome it after about 20 seconds the rpms drop down and it gets quiet again. Is it what it supposed to do. The outer pipes are exhausting not the inner. Is that right?
Not sure, but it’s less restrictive so there’s probably some minimal gains. Not really worth putting it on a dyno just after doing this little “mod”. I’ll probably dyno after getting an e85 tune.
I have a question!! I removed all four of these plugs and as always, when I first started her up (cold) she sounded absolutely great. However, after about 15 or 20 seconds it got quiet, just like normal. Just like it normally does. Is there any reason why the exhaust valves still closed even with all 4 plugs, unplugged?! It was a significant reduction in sound quality after about 20 seconds of running. Hate it!
It shouldn’t do that. Did you unplug them while the car was off or after turning it on? Turn the car off first and then unplug. Valves are set to open when the car is off.
@@cartune_netwerk yes, I unplugged them all while the car was off. It blows my mind. All 4 unplugged and sounds great at first, and then gets quiet as soon as you put her in reverse or if idles for about 20 seconds. Sucks.
@@DKeithAllen1 interesting. I know there’s a $300 module that does the same thing and gives you remote control ability to open and close the valves. Maybe try that. Sounds like you’ve done it right though so maybe take it to an exhaust expert and see what’s going on.
@@PhuLy8788 I’m about to take it to a muffler shop and have them forcefully go in and remove those stupid ass valves. There should be a switch that allows them to ALWAYS remain open
Thanks! I just did this, and it sounds great. It's louder but still an elegant beast sound.

Likely less restrictive so that’s probably the result your seeing
Does it have any lights on dashboard

Good stuff! Will definitely be doing this before I install an aftermarket exhaust
Definitely going to do this! Thanks for the upload.

Yeah I’ve seen that video. Definitely nicer to have the adjustability on the fly.
Can we get a video for this . I have an Lc and would like to hear the difference
Just did the his on my LC and wow what’s difference. I did end disabling via trunk as I wasn’t comfortable leaving wires hanging . Either way worth it for sure.
you put the wires in the trunk?
I'm doing this. Can I use the standard scissor jack to get more clearance underneath? I'll put rear end on stands.
Did someone start the car or was this a remote start ??? Plz tell me a remote start is possible

Awesome dude!
Nice car! I also have 2018 LC (smoky granite mica) - after unplugging the valves did you get any codes while driving (check engine light)?
No CEL. Nice!
Awsome Car Pal. 👍👍

Check out the forums, I think there's a bit of a difference in how to make this work on convertibles
Have you solved the issue ?

awesome video thank you for sharing you got my support
i love ur plate broo
Any performance changes due to this mod, i.e. increased speed, more torque etc?
Not sure, but it’s less restrictive so there’s probably some minimal gains. Not really worth putting it on a dyno just after doing this little “mod”. I’ll probably dyno after getting an e85 tune.
Any codes get thrown .. also is your gas effected
Thanks for the info
Does anyone know the Workaround for the new IS350F?
👍🏻
Mo power baby!
Can I disconnect the harness at the module? Where does the module located for the exhaust valves?
yes, I think it's near the battery in the trunk
Thx
So when can valve open on sport+ mode ? If you don’t remove the clips
It's variable to when you push the accelerator but yes Sport S+ opens up the valves most of the way
I just u plugged all 4 on my 2018 LC. Do I need to cover the two hanging connectors or the two attached to the exhaust ?
yeah probably a good idea to put some dielectric grease and electric tape them so they don't get corroded over time
@@cartune_netwerk It would be better to ID those plugs and buy 4 plugs to cap everything off.
how many are you actually unplugging? is it 2 or 4 connectors? thx
2 on the coupe. 4 on the convertible I believe
I only see 2 plugs for the valves for the LC 500 Convertible... does that make sense?? Thx
Yes, the convertible only has 2 harnesses. I believe Lexus just combined the harnesses in the newer models of this car and the convertible.
Mine is like that. Put some blue painters tape over the male and female connectors
Can the harnesses be disconnected at the valve control module? Where is the module located?
Does that can be applied for RCF/GSF exhaust?
No, just the LC. Factory exhaust on the RC F and GS F doesn’t have valves
@@cartune_netwerk What about the IS 500?
Do I need to buy anything or just unplug it
just unplug
Did you get any warning light ?
No CEL in the dash
Can you access the fuses with the car on the ground (I.e. Just wiggle your way under) or do you need a car lift?
Yup, you should be able to access without jacking the car up. Just make sure you have enough room behind the car
