ERA GT40 Gets Active Exhaust

ERA GT40 Gets Active Exhaust
There is a company in Monterey Ca. installing their active exhaust on an ERA GT40. I will be posting pics as soon as the coating work is done.
 
What is an active exhaust?

A EXUP valve?
A noise test passing valve?
A varying size resonator based sound canceller?
 
Sending the before pics..

The system has been designed to offer 3-4 db sound decrease on demand. The results are great , for those of us who want it all. Long periods in our machines with or without load exhaust sound levels.
