There is also the xpipe merge location moved forward vs the traditional OEM merge location of many pipes. I imagine this further reduces the gain attributed only to the header.

I'm not sure what you disproved...
Headers and forward merge on the xpipe are both adding additional power here. The dyno's by the OP only show the difference between oem xpip with test pipes and the full becker header system with forward merge xpipe. So the full power gain cannot be attributed to the headers themselves. The links I provided demonstrate that a decent amount of additional power is made simply by using an xpipe with the forward merge xpipe. You stating that you made ~10hp with headers over the Gintani pipe somewhat proves my point. Quote:

There has been some federal crackdown on the sale of devices that defeat emissions. No company wants the feds coming after them and fining them. The fines can be pretty big. Get someone in a neighboring state to order for you.

Your point is taken about my dynos not showing only gains from the headers. In my case I wasn't going from a catless xpipe with x further up, to headers, which most people probably wont be. So to me it doesn't matter as long as my new setup made more power and sounded how i wanted from the old setup.

Here is a go pro sound clip to give you an idea of what my setup sounds like in varying driving conditions.
Initial start up, part throttle cruising, 2nd gear pull, parking garage rev.

Gains are gains, even if there weren't gains I would still purchase the header system over any other x-pipe on the market for the sound... V8s with Xpipes closer to the motor has always been a gain in performance for most applications, numbers are great for the price and the system is a really good deal. I might move forward and pick a set up! Thanks for the information and post provided!!!

Quick question as I only read the first page and certain sections, excuse me if this has already been answered but you made +15 more over test pipes, did the new headers come with a new x pipe as well? It looks like it's not just the headers. Does the new x pipe have secondary cats still in place? Looks like it's 1st section of x pipe

Then the results aren't technically +15 over test pipes. Secondary cat delete gives a bump in power as well. Why didn't op just put the headers on with sticks pipe and test pipes and report back?
