If you are after power, the shorties will be a disappointment. The scavenging that the long-tubes allow for is really noticeable on our cars. I guess a snap-shot comparison of short vs long tubes would be:
Shorties:
- make very little power difference
- easier to install
- emissions legal
LT Headers:
- significant power over stock
- more "difficult" to install (difficult is in quotes because there are some guys on this forum who can do it in their sleep, and then there's others who swear that they would rather wreck the car than re-install LT headers)
- technically not emissions legal because you move the cats
- allow for a much more pronounced exhaust note over stock headers
I'm sure the others will fill in any bits I may have left out: the diameter of the stock header tubes. That is something I don't know.

The main thing positive about shorties is that they'll dress up your engine compartment, but not much else. Long tubes are more work to install but the final result is worth the effort. The power difference is something you can actually feel, especially if you have the car tuned to utilize their full effect and make the most power. You'll probably need to be tuned anyway because many systems eliminate the rear O2's which necessitate having the car tuned so that you don't a constant check engine light. I have the LG street system with the high flow cats. I installed it myself at home on jackstands and did it over a weekend taking my time and not rushing. Along with some other bolt-ons, such as a Callaway Honker intake, there is a very noticeable power increase. I also had my car tuned by ECS and my car still passes NJ inspection.

Unless your state inspection is a real bear, I would go with the long-tubes. Any of the big-name brands work well on these cars. I currently have Kooks, but have used Hooker Super-Comps as well.

Long tubes will improve the torque curve, thus improve average power over shorties. They will also provide more potential on a highly modified car if you go down that road later. But shorties are not to far off for just a bolt-on car, as headers themselves are only good for ~15hp at the bolt on level. The extra power is from a low restriction air intake and maximizing the tune.

Get some 1 3/4 longtubes unless you have big plans for this car later down the road.
And no it wont connect to the stock h pipe if you go longtubes.The majority of longtubes company come with thier x pipes that connects to the stock ti.

Interesting thread,
I ordered my Kooks 7/8 Longtubes incl. the X-Pipe complete in 3 inch incl. coding. Other than that I have the VARARAM Air Intake and Powerduct but I plan on a camshaft mod late this year or next year. I will dyno the car after the install and hopefully will have some nice power and sound gain! I will leave the stock TI system what I learned should be a good combination. When all of this is done I will post my experience.
Greetings, Rouven.

Order them JET-hot coated.
Had TPIS before, now these. Like night, and day.

I like the LG Super pros for max power. The streets are also a good value if you plan just bolt ons/mild cam. These bolt up to your stock exhaust.

Hey Jetz,
yeah I ordered them Jet-Hot coated sterling silver 1700° for the longtubes and the X-Pipe, Maryland was giving me a pretty good price for that
Do you guys know if there is a performance difference between the Kooks or LG Headers? I was told that Kooks is the best system with the most power gain......we will see! Plus I ordered the 3inch system and 7/8, I guess this should be the best system together with my Titan stock exhaust.
My system should arrive in three weeks, then I will know more!

I have decided on shorty headers to keep it emisions legal and to keep the lightwieght Ti exhaust on my 02 Z06. I am wondering if the cost is worth it to go to the stainless steel B&B over the much cheaper and coated BBK. The B&B seem to have a much more detailed collector, but I like the idea of the ceramic coated. I know this has been discussed at length on many threads, but has anyone put on both of these and can tell me the real differences rather than just personal preferences?

i just installed the LG streets with high flow cats..which compliments my vararam intake very nicely...took me 12 hours not rushing anything and taking my time...i love how the cars sounds now.and the power gains were very noticeable...i have not sent my pcm to have it tuned yet..but i will in a the next few weeks
