To clear things up, my car is very loud. I don't disagree with anything you have said and was simply asking if it increased performance...or just made it louder.

The stock exhaust has butterflies in each muffler right at the exit. Opening the butterflies makes the mufflers straight through. The power gain is negligible. However, the "mod" is literally just pulling a fuse. It gives you louder exhaust between idle and 3000rpm. If you want full control over it while driving, there's a 100 dollar controller. From the factory, the valves open between 3000-4000rpm anyways, depending on how much throttle you use. Below that, the car is as quiet as a Tahoe.2010 RX350 AWD

I know how this works. I don't know why you keep thinking I am confused about something. I know the factory will do things to make a car quieter at the expense of HP, so I wondered if this was one of those things. That is all.

I have a 2010 ZR! and installed the mild to wild system. Only took about 15 minutes and I can control the sound with a small keychange type remote control. Works great
