Waste gate dumping, examples if possible I'm working on a TT 5.3 project, and wanted to know if dumping the WGs into the atmosphere VS routing them into the down pipes had any pros/cons. If I run dual cut-out, when open I should still get my jet plane sound like in the video below?

In most cases, recirculation will hurt power. However, If it we're my street car, I would have properly sized turbo(s), downpipe(s) and definitely recirculate. The open WG noise would kill me.
I have personally seen plenty of cars make 1000+ rwhp with recirculated WG's. But people are correct by saying 99/100, open WG's are more efficient.

If you decide to run the dump tube to atmosphere, try to keep it as far away from the compressor inlet as possible. At full tilt, the turbo can recirculate exhaust gas from the "screamer pipe" if it dumps nearby.
