Shorties VS Long Tubes, s

Dan04COBRA · 11-07-2003, 09:04 PM

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

And what about the difference between stock and shorties? 5-10hp?

Dan04COBRA · 11-08-2003, 02:45 PM

From what I've seen on dyno graphs, 8-10hp if they are Jet Hot coated.

yeah, theyre not as bad as you think...

i dont think long tubes are necessary without quite a few mods

So, my mid lengths should be somewhere in between<IMG src=smileys/smiley16.gif border="0">

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?

Shorties are a 5-6 hour job for a shop. They are rather easy to install, just a tight space to work in makes for slow progress..

Majority of shops charge 60 and hour...I'd say anywhere from 400-600.

I put mine on in about 3-4 hours. But thats on a 5.0.

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 wasMM&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..
