I am always skeptical of manufacture's claims especially when you get into single and very low digit numbers. Looking at the dyno the torque would certainly be able to be felt if the numbers are taken as accurate. That is one dyno graph that they decided they would show everybody and maybe (just maybe I don't KNOW) there are several hundred showing a 4HP increase. I personally can never assume that the numbers provided by a manufacturer (even the best of them) in marketing materials are repeatable. If there header can truly hit those numbers with no tune then why are the rest of the headers showing 5 and below? Now, of course I could be totally wrong on all of this but I will stick to my opinion on the matter.
Oh, and it isn't BHP it is WHP they are showing since it is done on a dyno. If it was actually BHP then the WHP number would be much lower. Like how the car is listed as being 200 or 205 BHP but in reality the WHP is not even close.
