Those seem like a couple farm boys building tractor pull headers. Even if they aren't, the headers on the Titan/Armada are not problem areas like they are on other cars. They are pretty good stock. Without a set of good qualitiy long tube headers that work with the electronics, replacing the headers on our vehicles is pretty much a waste of time. Mossy is the closest to developing them and Nismo was working on a set also. I wouldn't expect much in the way of added performance, but some smaller gains as the stock is that good.
