I already found a buyer for my AMS downpipe as I have been wanting to switch out to an o2 dump one....want the most out of the setup etc etc and my car is already stupid loud anyway.

Regardless, I was talking to Chris Carey a bit today in emails and found this..

The thought is to run this with an external gate in conjunction with my internal gate. MAP did this on their 722whp stock frame evo 8 shop car and it worked great. It allows you to easily implement a nice external gate without sacrificing twin scroll. Just going to an external gate without keeping the internal one gets rid of twinscroll. The only other way to keep it is to use two external gates on your manifold which is like a 2k manifold setup...no thanks.

So I was planning to get MAP's downpipe anyway so I figured for a few hundred bucks I won't have to worry about my wastegate opening up as I believe it was before.

Everyone's thoughts? I know more boost != more power but for the sake of discussion ignore that and assume it will

I see no downsides other than possibly spending 200-300 extra dollars on something that may not work...otherwise it won't hurt anything else I don't think. It's the best of both worlds as Chris said and I believe its the same setup AWD motorsports uses to hold boost so well on their stock frame cars.
