I honestly do not understand how headers can do nothing on a platform that it is a well known fact that the stock front manifold is very restrictive.
I look at it this way, when you breath what is easier, breathing through your mouth, through your nose or through one nostril?


Btw my fathers former college roommates cousin was able to triple his horsepower by adding headers........................
Stock manifolds have shown to support 600whp, yet some still claim they are a severe restriction with 200whp. Keep buying that snake oil.
