Yeah, I was joking about that... Even saying the words "header" get at least a 15 hp increase, due to the fact that the velocity of the word coming out of your mouth hitting the front windsheild will in turn push the frame of the car faster during acceleration... Kinda like a sailboat... And the louder you say it... OH!! each decible increase is a Hp increase... HAHAHA!
I am hoping for 10hp low end... hoping... And being able to rev harder and faster...
A.Van: Total cast of my setup including mufflers and all that... $800... Now, that is including piping, mufflers, two High flow cats, flex piping, and install... You could just get all the stuff and torch it on yourself and it would drop the price about $400...

But that means, you have to bend and get the piping too...
I highly doubt this will get off the ground, since not to many people want to pay that type of money... But you never know...
