can't seem to find a manufacturer, I've checked out BBK, JBA, and MAC. they have unequal lengths only, or so it seems.</P>

 

I don't know if they can make an equal lenth that would fit, I put longtubes on my '02GT and in all honestly those baby's barely fit.

 

i guess headers get moved off my list unless i make a friend at a smog stop. from everything i could find, it seems that unequal lengths are kinda worthless unless you have a turbo or supercharger setup.</P>


i found the following on the internet from allfordmustangs.com. they used a stock 5.0 for each of the tests. Hopefully it will help someone down the line.</P>


oh, has anybody come across something like this for a 4.6? apparently the 4.6 reacts better with 1.5" tubes as oppsed to 1 5/8". at least for stock and lightly modified applications</P>

here's the torque graphs</P>

Hey thats great helpful info for alot of people looking to make the same decision you were

 

Unfortunately, there are no equal length shorties for the modular mustang. not enough space for them.

 

bummer, looks like there's just no getting around a supercharger. hehehe.......</P>
