I just got high flow cats and a new muffler, and thinking about headers. Should I put the exhaust parts, cats and mufflers first and an electric fan (with existing exhaust, JBA Shorties) and wait on the headers, or get the headers first and wait on the fans. I saved up money for a while now and really want to get some more done to my truck. If e-fan, what is the best for the price? Headers too?

 

Go with Pacesetters long tube headers, they're around $450. Get Flex-a-Lite VSC Fans, they make some for your stock radiator and some for the new 34" radiator. Look at some of the sponsors sites for prices on those items.
