I own a 2001 F-150 4.6 5-speed, I have already added a superchip, the K&N air system, and I have true straights on it. It sounds great, I love it, but I'm looking to buy a mass air sensor, and headers next. What type headers does anyone suggest. I am drown towards the JBA headers myself. and if i put headers on is there any thing I need to do major.

I also wanted to buy some throttle body spacers, but every where i have called, they say the TBS will not fit because, I don't have a-nuff clearence between my hood. Any suggestions?

 

JBA or Gibson are good brands

 

JBA's and Gibson's are both nice. I personally have the gibson headers and haven't had a single problem with them. With the Gibson's you get the same quality or better than the JBA's, but at a cheaper price. I compared the two before I bought them and didn't see any difference between the two, and the only reason I chose the Gibson set was because a drag racer friend of mine said he doesn't any other brand but Gibson. Both JBA's and Gibsons are nice, it's just up for you to choose.

You also don't have to do anything major when you install the headers. It just requires patience and a bit of time.
