Screamer pipes

Doing an article on them but can't get much information about them!

Am I right in saying they are not a dump valve which releases fresh air pressure when you lift off the throttle instead they work on the exhaust side of the turbo via the wastegate so when you are at full boost the excess exhaust is vented to the atmosphere?

You will not believe the arguements over these so I'm on a mission to settle them!

I still get amazed that Ferrari fitted one as standard on the F40
