It's a butterfly valve to bypass the majority of the exhaust for more power when he chooses, when he gets the 3S swapped in.

Thats what I though.
So, electronically controlled, you can let more exhaust flow for more power?

Yep, basically you put it before anything ideally (cats, resonators, mufflers) to simulate an open downpipe.

You can also do it with a throttle body. My previous Celica had it done with a 60mm TB on 2.25" exhaust tubing. The difference is it's manual vs electronic. I plan on doing it again to my actual Celica, and it'll be manual again. There's no motor that can go bad that way.

This would only be beneficial to a Forced induction motor, correct?
Would that not cause a decrease in back pressure on a n/a, resulting in a loss of power? (if used in the exhaust)
