I think I read some time ago (probably when I first bought my Yaris) that the original muffler has a spring loaded bypass valve internally. This is supposed to open when the exhaust flow reaches a certain level. I definitely hear my 2nz-fe get louder at higher RPM.
Might just be a case of remove the spring and add a control cable...
