Video/audio of open or return wastegate systems?

Evening all,

 

Looking at changing manifold, downpipe and midpipe soon and was wondering if anyone knows of some good videos giving a reasonable audio to show the difference between having a screamer pipe vs having it plumbed back into the exhaust?

 

Currently I do have a screamer, but going to a twin 45mm wastegate setup. Is that going to be a lot louder or will it just be the same amount of noise coming out of two pipes?

 

I am also assuming the advantages of plumbing the wastegates back in is less noise and also heat is then going out via the exhaust, rather than somewhere near the engine bay - correct me if I'm wrong!
