"What's so interesting?" you say, "They look exactly the same!". Yes *that* is what's so interesting. I made no power, nada, zero, nothing, no where...

But notice about 800rpms before and after VTEC, there's an interesting jump in power and torque, it's not more than 5 lb-ft at any given point.

Now before anyone goes and say "see, I knew they can't make a better header for cheaper", I'd like for another person to do some dynos. There is something strange that I can't figure out. Notice how the AF ratio on the run with header is more lean? Well from the last dyno, my peak run was the most lean of the 3 runs taken that day. Looking today, I would have thought that since I am running yet more lean, should have made something somewhere.

I guess DC can claim that their header makes mid range torque...
