If I use your analogy long tubes are worthless since the power is all in the high end, not so good for a DD.
I don't usually cruise around at 6000 RPM, but I do cruise around at 2000 RPM and the shorties sure help down there.

This is your opinion, The pick up in the low to mid range in torque is more than worth it.

Do I know what my car does differently from before the header install and what it does after? Yes.
Do I have to worry about the $25,000 fine for removing my OEM Cats? No
BTW that is up to $25,000 for removing or Modifying a pollution control device.
Are Long Tubes really worth having to pay a fine that large? No.
So knowing someone that did get a $15,000 fine for having other than OEM cats on their truck (High Flow Cats on his F-150) that was reduced to $1500 after putting the stock exhaust back on it just is not worth it to put on long tubes.
I will stick to the shorties that are CARB approved, the OEM Cats and resonators and enjoy the low to mid range usable torque that they offer.

Tell me about your headers, how do you like them? I have decided against the long tubes for ca standards as well as the unreasonable sound. I may consider going with the shorties for the little added upgrade.

Nope haven't ordered them! Just about to put coilovers on, and just ordered wheels so I'll need to save again!

Don't listen to redfire. Shorty headers will give you a noticeable torque gain. He is obviously uneducated when it comes to shorty vs long tubes.

Ahhh yes, trying to justify wasting your money on shorties. I see what you did there!
I do not need to justify my choice to anyone since the gains are there and more than one person has dynoed them with much large low to mid range torque and HP gains than long tube. The only place long tubes did better than the shorties on the 3.7 is in the top end. Since corner carving uses more of the RPM range than just top end no justification is needed to you or anyone else.
And then you have the Raspiness that you need to get rid of or drive you crazy if your car is a daily driver. After having ridden in a car with long tubes there is no way on God's green earth that I would have put long tubes on, even if they were legal for other than off road use.
Oh as for the comparison
Same car in the Shorty VS Long Tubes, so they are a waste, I think not.

As for me it wakes the 3.7 up, it gives it a modest torque bump where the 3.7 needs it the most in the low to mid range. It is probably the best legal performance mod out there that actually changes power over just enhancing it like gears would do. Then there is the fact that after you car is old enough for smog you don't need to find a crooked smog station of put the stock stuff back on to get it to pass. I miss the Beach, but that is all I miss about California.

Most of my knowledge/experience is from a long time ago with Chevy engines but let me list some generalizations that applied then and tell me if they still hold true (my memory may not have these quite right):
Bigger diameter tubes are better for larger cubic inch and/or higher rpm engines.
Smaller diameter tubes and better for smaller cubic inch and/or lower rpm engines.
shorter length tubes contribute to a higher rpm torque peak.
Longer length tubes contribute to a lower rpm torque peak.
On a side note the header collectors I see on headers available for the 3.7 V6 (especially on the short tube headers) all look too short and inefficient.
