^Glad you chimed in Ryan - yeah I remember you saying the power really got uncorked with the headers. Again if you don't need emissions testing then they really are a great way to go. If you do have emissions you'll need to fit high flow cats and play with o2 spacers on the rear sensor in order to avoid a CEL light (or using a tune like the Euro 2 which is a DME update) - note that aftermarket tunes that code out the rear o2's like Active Autowerke to the best of my knowledge will not pass emissions because it won't pass readiness
