According to research I've been doing lately...
In vehicles producing under 400 RWHP the HP gains, or loss between Shortie headers & Long tube headers is non existant. From 5 sources I've researched from, Shorties provide more low end gain. Long tubes produce high end gains. In the end, cars under 400RWHP, the cost of Long tube headers & effort needed to install them is not needed.
According to the people who have done the testing and dyno runs, both long tubes & shortie headers produce the same hp gains, just in different places of the HP & TQ band.
Unfortunetly, I just cleaned my cache and some how lost my history, so I do not have the website URL's I got the information from. Take it for what it's worth ;)

Now that I have an O/R X pipe, would shorties be good for me? I did read in many sources that shorties were very good for torque...... How much is it to install them?

Here's the thing you do NOT realize when comparing the two.
You're comparing the peak power and torque with dis-regard to the curve.
I believe it was MM&FF, the one with the Red Saleen did a mid-length install to compare to shorties. I'll be damned if they didn't have a gain of 20 some odd horses and ft.lbs. in the middle of the curve.....with the peaks being about the same. Now imagine Long Tubes over Shorties........
well to be really correct none are the best..the one that is right would be one you tune just for your car as welding them together and have differnt primary tube lengths to help with temp in the compustion area and flow this can be done near the collector areas..how this helps..

I DID realize this, the problem was, not everyone here is going to understand that, and to save myself the time of explaining the differences you'll see in the hp/tq curve. That will be balanced out assuming you do more modding and stay under 400hp. But, good eye for catching that

Ok, so here's my combination questions:
I have an Off-Road X-pipe(with magnaflows) and they told me that long tubes wouldn't fit unless I customized.. cool' Would shorties help me in any way? would they hurt my performance? What other mods do I need to help the set up that I currently have???
you could get the Bassani mid-lengths like I did. They'll still have to do a little cutting, but those headers will fit your x-pipe. A long tube setup would NOT fit, because you need a smaller x further down the pipe, not the current one under your car. Shorties would fit, but u'd get more of a benefit from ml's.

You'll get a more flat curve from long tubes than say shorties, but $400 you save for shorties can be used for another mod to gain the same as if you had long tubes.

Is it true that an off road Xpipe could produce the same or even more power than long tubes?? I was reading some numbers and dynos on this.. Ever heard of this?
What's the difference in price between the mid lenghts and shorties?? What about performance?
