I was wondering who makes better headers Mac or Gibson? I hear that Mac is good but i dont know its statistics can anyone help?

 

If you do a search here you will find that shorty headers provide 0hp. When reading the ads they only say increased performance or 15hp with modifications. I do think that Gibson and Mac make a quality product itself in fit and materials but the $400-$500 exhaust manifolds aren't worth it. Longtube claims are around 30hp.

 

macs are way cheaper and a lot of people like them..what kind of truck do you have??

 

I have a 2001 V6 4.2 F150, if you know of any other better headers than mac and gibson that are at a reasonable price, post them
