Headers vs 340 manifolds

This is just stupid. It's been proven time and again on dynos and dragstrips and the street that headers stomp manifolds all to pieces. Saying stupid crap like "if the engine's not tuned for headers......" is just dumbfuckery in the name of arguing. The FACT is that headers will kick manifold's asses every single time, because anybody in their right mind will TUNE FOR the headers. Anybody that wouldn't is just a dipshit.
