Long Or Short Tube Headers

[STEALTHBOMBER]

so im looking at either getting long or short tube headers for my EXT i was just trying to figure out which is better. what are to pros and cons or each, any input would be great thanks

I got shorty headers in mine. For a V-8 they are better, i believe more low end power.

Long tubes are the best for making HP.Waiting on dynatech to make those for the 6.2.

Shorties are a waste of money with the way the stock manifolds flow, shorties will give you 5-7 hp, not worth the cost, go long tubes or stay stock. The proper long tubes will give you the most hp 15-30, and the best low end torque on the dyno.

Are long tubes available yet? Also, will long tubes increase cabin volume? I have a cat back now and the sound is great at highway speeds. I am just concerned that headers will make the sund level uncomfortable on long rides.

I think they are out for the 6.2. Any exhaust mod will add some noise, it's what happens when you increase power, having said that it sould not be much louder

I just finished a search fr long tube headers. I can only find the shorty's for the 6.2. Has anyone alse had any luck?

D3 claims a 21 hp increase using their short tube headers. I am confused. Can we get that type of gain with shorties?:

Make sure you are standing there before and after the install and the dyno run because 21 hp is not happening with shorties on an 07'

Please let us knw when your long tubes are available

hcvone is correct, on a LS2 a good set of long tubes will make 15-25 the higher number would require high flow cats. Shorties might make 5 on a good day, no way will they make 21. D3 probably forgot to mention they got the 21 after the shorty install AND a very aggressive tune(ie. lean) on a cold day.

Thanks for your input. Do you know if any one is making long tubes for the 6.2?

403HP My comments on the ls1/ls2 and exhaust comes from my personal experience with these engines in Corvettes. Mr. Chevy did a pretty good with the factory exhaust so unless you make a big change(long tubes and high flow cats) you won't see much of a gain. I have no experience modding the ls3 in the Escalade but having looked at the exhaust manifolds on my 07, I see the same basic design as the Corvette and would expect similar results. Now for the hard part, finding someone making long tubes for an Escalade. There are several good header manufacturers of long tubes for the c5/c6 (Kooks, Stainless Works, LG to name a few). I know Stainless Works and Kooks both make headers for trucks so they might have something for the Escalade. Good luck in your search.
