Do you mean the exhaust valve that is actuated by throttle position for variable exhaust pressure, theoretically keeping the low end torque, while still gaining top end power? I have seen something like this somewhere on the internet... or sold at Speedy... I'll have to look again.

thanks that was what i was looking for
i planned on instaling this so i can open up the exaust on race days without having to buy a down pipe, i also plan on getting a exaust y fitting just so i can run stock exaust and then open when the oportunity arises.
