"It took me a full day to install the headers, but they are work the work and money. There is a definite increase in torque and horsepower, and a decrease in RPMs by about 500-1000 (60mph). I haven't had a chance to see about improved fuel mileage, but am guessing it should increase a little also." —Owen J from Black Hawk, SD bought a JBA Cat4ward Headers for a 2001 Ford F-150.
