Can someone explain how they work?


Ben.

 

YOU WILL ONLY SEE SCREAMER PIPES ON CARS THAT HAVE AN EXTERNAL WASTE GATE & instead of plumbing the exhaust pipe back into the down pipe it exits straight to atmosphere which makes it bloody loud ,the external waste gate is used to regulate boost pressure the same as a wastegate actuator does on a conventional turbo do ,but the external one,s tend to be more accurate and used on big power engines .

 

Simple as that?

Thanks buddy

 

also, they are for the cool kids lol!
they are bloody loud though, mine dumped straight out and down to the road.

 

They sound disgusting.

 

I agree mines plumbed into the exhaust.

 

Screamer pipes arent everyones cuppa tea.. You either love them or hate them. I think there cool as hell lol but everyone has there own opinion.

 

there's nothing stopping the wastegate outlet pipe being silenced and therefore not 'screaming'

 

you dont need an external wastegate to have a screamer pipe, you can make them on rs turbo style exhaust housings where the wastegate penny is offset from the rear turbo wheel

 

Thats usually refered to as a "divorced port"
And penny flaps creep so usually let gasses past even when not on boost,


I love external wastegate sound, the sound is also reflected from the design,
The one on my old focus went straight to floor origionally but was echoing back extremely loud,
So i had a 30 degree angle attached to aim back slightly and then it sounded spot on,

Pics of mine origionally
Here you can see the wastegte with the take off



And here you can see the screamer pipe poking straight down
