Its all about velocity, and efficiency. I am not saying everyone is buying the wrong size header, if I had high flowing heads and big cam in mind and didnt have to smog test I would be right in line with some larger tubes. But for now and up to 350HP I wouldnt give up the torque and useable HP.

Yes I have seen stock headers on a mustang. FYI: I've been mod'ing stangs for years. At 350hp or around there (which would equate to just about 300rwhp) I think 1 1/2" headers are really going to hinder the cars power when you get up to 260-300+rwhp. They might be good for stock headed cars, that don't plan on heads in the future. Headers aren't really going to help on a stock headed(unported), stock intake car. And they surely aren't going to be a better choice than 1 5/8's on a mod'd car. So why get them?
