I am sure Nate edited the post since the results were from the manufacturer and not their own numbers! I am quite sure that IND will post their independent numbers soon after they get the first set installed on a car!!!
Peak numbers aside, it would be nice to see if the headers will have any major effect on the top or bottom of the torque curve!
No reason to apologize, I remember there were results in the 27hp range but this was with a tune. I personally don't expect much of a gain with these for the amount of money needed to be spent.
