Sorry, but I'll agree with the statement below:

Would be interesting to see this back to back to back test with a popular - x pipe and 3" cat back setup. So you'ld have the ideal back half of the exhaust, and then the only variable being the 3 different header sizes.

The exhaust manifold (aka the headers) are
usually always the most restrictive part of the exhaust. Though technically without a tune you cant really benefit from all of the back pressure you have just released, but regardless it's an interesting idea for these guys to do it and obviously for vendors among the boards will probably try to stock more of the one that is chosen to produce the most power, and then aggressively price it for the market of Camaro guys.
Subscribed to see what these gains are!
