maybe if you had like 500 feet of piping...its *******ly insignificant you lose a fraction of nothin for what its worth but the benefits outweigh that ie the 500+degree less running temp

 

That's true. I wouldn't want mine under the hood anyways, but not in the back of the truck either. Just at the end of that header. Down where there's nice cool air, and no short supply of it either. Of course that instantly turns it into a nice weather only car. But, who cares, I hardly drive in the rain now anyways. LOL.
