Dyno runs are never worthless. This will give a VERY good idea what power to expect. The exhaust will help some, yes, but the headers will make a much larger difference.

I'm not gonna argue with you about it. I agree baselines would be nice, but I've not found a single person on this board willing to truely test a product. I'd be happy to just see a dyno graph with his setup. I know enough about exhaust to extrapolate about what the headers add.

I see too many people buy things here without any type of testing. That's just nuts. We tested everything on the Tacoma board.
