Horsepower increase
I have a 2018 LC500, I purchased the module to have a remote on the exhaust to open or close at will. I ordered the one that was programmed open and you have to push the remote to close it. I do not ever need to change the exhaust as I love the sound so much, and it does seem to have a better response all the time. Just fyi....

I bought the module and I love it. To be honest I just keep the valves open 24/7 now so there's no real need to buy the module if you plan on keeping them open all the time. You can just disconnect the wiring that controls the valves and call it a day. I guess it is nice to have the remote if you want to close them or have the car control them as normal. There are 3 settings...open, closed and oem car controls the valves.

It's not difficult to install the valve module. There is one plug that is extremely difficult to reach. You need to squeeze your hand into a very tight spot to connect it. I probably spent 10-15 minutes alone trying to get that one piece connected and I have fairly thin hands. Dropped plenty of F bombs in that period of time. LOL Worth it in the end though.
FYI.....IMO the exhaust sounds in his videos sound way more extreme than what I hear in my car. I think he had the mic placed next to the exhaust while he was recording.

@TunedbyLoi has a tune for the LC500. Pricey but if you put headers and exhaust, it'll probably give you at best 45 extra HP. He also does transmission tunes for it so the gearing would be quicker. He is the only one for now that tunes the LC500
