Headers

A bit late into the discussion, but that article is not comparing in an unbiased manner:
http://www.fourwheeler.com/techartic..._long_headers/
They're comparing to stock, which is the point of the matter. The problem where you need to pay attention is that the Shorty is using a single exhaust CatBack setup, where the Long Tube seems to be running full duals without Cats. That invalidates their stand of Long Tubes being better.
That doesn't prove they are worse than Shorties, only that the results are biased, and can't be taken at face-value.
I'm interested in the comparison because my exhaust is pretty rusty, and all clamps have been removed in favor of welds by the previous owner. I've been trying to find unbiased comparisons of shorty + Dual Cats + full Dual exhaust (with Crossover) vs Long Tube version of the same. Most articles I find have the emissions equipment on the shorties and are deleted on the long-tubes.
Still looking.

So, why aren't you taking your truck to Germany? There are lots of them over here, and we all get along fine. The annual inspections are run by a bunch of ***** (wait, can I say that here...?), but other than that, stay away from parking garages and life is peachy. The only issue I'm running into here that I didn't face being stationed in Arkansas is the winter snow/salt build up and ensuing rust if you don't keep after it. But, you are going to have that with any vehicle, not just the trucks.

I know conventional wisdom will tell you at least sometimes that shorties are better for low end, but there are a lot of people who say that LT's will give you a better increase all the way across the board, including low end and with quite a big advantage higher up.
Here is a nice write up (there are more too if you just do a google search) showing gibson shorties vs some LT's, it shows the LT's with a power advantage all the way across the board.

Well, that wasn't a very good even comparison. The long tubes had a custom exhaust system with it where the shorties only had a simple cat back, and even at that the LT's only produced 9 ft lbs more torque, but at a higher RPM, and 14 more hp. Hook up that fancy exhaust system to the, shorties and run it again, so we get an actual true difference. Seems like every comparison test someone runs on anything, is always stacked in someones favor. In this instance I'd say stainless works had something to do with the stacking

Also look at these numbers and you will see that the stock manifolds and the shorties were tested at the same rpm, while once again the LT's are given their numbers at a higherPeak Numbers Horsepower Torque (lb. ft.) Stock 311 @ 5,176 rpm 345 @ 4,076 rpm Gibson 319 @ 5,176 rpm 346 @ 4,276 rpm Stainless Works 333 @ 5,376 rpm 355 @ 4,476 rpm

Well 08 we don't agree on much but I will agree with part of what you said. The cheap comment, is sometimes correct and sometimes incorrect depending on what brand of shorties you are buying. Some shorties are as much or more than LT's, especially when comparing to Pacesetter LT's. I'll take shorties hands down for a street header, because of their ability to make more TQ and HP over stock, and like you said, why do you need a header made for racing if you don't race. Installation of LT's on a truck is no big deal, and can be done by one person, but yes, shorties are an easier install
