I have an 2002 F150 Super crew FX4 , I just put an intake on it and am looking aat flowmaster dual exhaust. If i put shorty headers on will i notice a power increase is it worth the money. What is a good brand on headers.
I just put gibson ceramic coated on my 99 5.4l F150 4X4 and did notice a nice amount of power dif. I also have the superchip, K&N FIPK, flow master throttle body spacer (a waste) The headers really did make a diffrence though... I bought my headers on ebay of coarse....
actually the flowmaster was saying a flowmaster 5o series muffler and 3 inch Y back. The throttlebody spacer was not from flowmaster. I did not feel any difference with the spacer... therefore a waste lol. Most of my mods were done alone one at a time... so I could tell if it did anything.
