The Mitsu 3000GT has a similar system, not sure if the Stealth TT had the
same. It ran on one side of the exhaust then opened the other, not sure if it
was boost or RPM activated though.
My twostroke dirtbikes have a powervalve, they reduce the exhaust outlet
greatly improving low end, then mechanically open for high RPM's.
You wouldn't beleive how many people here in NJ throw out the
stock EXUP system, to put a regular header on...they make more noise
and go slower...it's the ricer mentality.
