Default OK place to dump my EWG?

I was working on my car today for once, and I am almost ready to fire it up. I need to dump my EWG somewhere. I am getting impatient and looking for an easy spot, and I found that it would be cake to dump it right into my turbine outlet. The photo is where I'd put it, I didn't cut out my outlet yet, or weld anything. I'm wondering if this would cause any issues as far as exhaust flow or turbulence.
What says MT.net?

Well thats about the least optimal for power and wastegate performance, you might as well use an internal wastegate. It should work through.

I assume running it to the DP is the better option...
I could make it even easier and vta.

I thought about that, and I was gonna put a flapper on it. I think I'll keep it stealth though and keep it going under the car.
Seriousness, vta I think it is. I'm just concerned about noise, basically just an annoying factor.

My suggestion is back into the exhaust.

vta will make most power. Make sure its braced though or that the tube us uber short or it will lead to cracking. if you're going to re-introduce into exhaust stream you want to do it way lower on the dp, like about a foot down from where the picture shows, and make it a smooth transition back in

I read Turbo Tim saying he stopped doing VTA because of cracked dump tubes. But I'm sure there's lots of people who have.

Vta it is.
I'm gonna brace it...no cracks for me. Looks like I need to order more tubing.
This car ran out of inspection in March. I took it apart like 3 weeks before it ran out and I said "it'll be back on the road in a few weeks, then I'll get it inspected. Lol. That turned into machining parts for it, fabbing/ welding **** up, getting new shocks and wheels, installing door bars. I'm estimating I'm about 2 weeks away from taking her off the jack stands.
I'm a little behind schedule....if you consider a few months is a little.

I love how thirdgen works: three examples of people cracking their vta ewgs, so he decides that the best choice.

Broke the EWG off the manifold. VTA is a bad idea.

Well, how relatively unbalanced is the BP motor compared to the supposed vast majority of other motors? It IS a vibration problem.
