Screamer Pipe Vs. BOV

[DeadlyScone]

Kinda new to turbos, but my car is equipped with a screamer pipe(dump pipe) My question is that if i wanted to say hook up a BOV what would i go about doing this?
Do BOV's just release "air pressure" versus raw exhaust? Do you need to hook up the EWG lines differently? please teach me about this stuff .

Blowoff valves are on the intake side of things, and screamer pipes or whatever are to split the wastegate exhaust flow to open atmosphere and be loud as hell when the wastegate opens.

So much wrong in your logic.

You already have a blow off valve, it's on your upper intercooler pipe. If you can upload a picture of your engine bay, I'll show you everything you need to know on your setup.

Google is a wonderful thing, look what a 30 second search does!

Your blow off valve takes the excess boost and releases it when your rpms drop, an external dump tube, your screamer pipe (really ricey term btw ) opens when full boost is reached and "dumps" the excess exhaust causing the noise.

Its a lot easier for someone with knowledge to find what they are looking for. Give this guy a break.
Your throttle pedal is connected to your throttle body which is located behind your engine by the intake manifold (opposite the exhaust)
When you let off the gas, the plate closes inside the throttle body so pressure builds up between your turbo and your throttle body (air has nowhere to go). To prevent this your bov will release pressure. With out going into to much detail, your exhaust dump tube is to release exhaust and has not much to do with your blow off valve.

Hope this helps clear some things up.
