That's a new one to me and I've owned this platform for 8 or so years... A "turbo header" isn't going to be something you come upon often and, if you can, absolutely get one. I ran a cheap eBay manifold for 5,000 miles or so. For $200 if you needed one because your OE had failed it's worth it, but otherwise prepare to put some time and skill into fortifying it. Gabi has a manifold for sale I believe, so you might want to check with him.
YOU KNOW! a whole year later I just noticed that was sarcasm hahah lol that's too funny. I cant belive I even said something like this I was so new to boost haha
