Significant increase in performance

I have a f250 2004 4x4 5.4 2v and am tired of changing headers. I had a model without EGR, just had to plug in the connector. I bought them to try and get away from cracking factory manifolds and rusty aftermarket leaks. I didn't expect any increase in performance. If I had known what a performance difference it would make I would have done it a long time ago, my truck has a 6 speed manual and I use a high gear on most hills and on big hills I usually shift to 2nd down the aisles. to pull, I'm only losing one, a huge gain in the lower midrange, I'm really impressed.
