What is a good brand/type of headers to get for a 93' 5.0 I am looking for performance, not looks. [&:]

 

im going bbk

 

I would just recomend skipping equal length shorties... they are a pitch to put in and there is sooooo much exhaust pipe in the engine compartment with them that the underhood temp soars... I had some and constantly had to replace my spark plug cables... I could have wrapped them with some insulation, but that looks hokey... I would get long tube headers...they offer max performance and less BS... any brand that has a good name should do (make sure to get some with a quality finish on them, as high dollar rusted exhaust components suck)... they are only really only pipes when it comes down to it...

 

I wouldnt necessarily say less bs

 

go with BBK or FRPP unequal shortys, ceramic coated.

 

Little theory: Headers collect exhaust pulse from individual cylinders and combine them to a larger pulse, with a corresponding lower pressure behind the pulse. This low pressure actually helps to draw in more air / fuel mixture into the cylinder from intake manifold. This is so-called "reverse supercharging". The reverse supercharging works best at a certain engine speed which is determined by the length of the exhaust pipe. The shorter the pipe, the lower rpm the reverse supercharging works. Of course, for any fixed exhaust pipes, the choose of working rpm is always a compromise.


There is actually a way of calculating header length for your rpm range, described in more detail in 50 performance guide book (go Amazon) and on some web sites.

There is a difference between shortie headers and long tubes, and it is not the length of tubing. Shorties are designed to utilize consequent pressure waves, which are weaker, but shorties offer larger rpm range (or sweet spot) then the long tube headers.


Almost any aftermarket headers will give you 20 rwhp + or - 5 rwhp depending on the chassy dyno. However, if you choose right parts that work right with your other parts you will get more. Best advice is to use tried and proven combinations, use people who have dyno tested their results. Saleen, and Rousch for example, or ford racing. Beyond that, you can do some calculations of what will work best for you, simply slapping aftermarket parts on is not the best way to go.
