COMPLETELY UNTRUE. They may look the same in a little low-res picture on ebay, but in person the differences between a shitty ebay header and any quality header are immediately obvious. And no, power gains are not the same on them either.

The Street Imports header?
He got what he paid for, that's for sure. Horrible welds, horrible collector, etc. I'll almost guarantee that's not the only thing that was changed, or that he also got tuning at the dyno that day.
