Make sure that you get a 10mm gear wrench. It will make a huge difference, especially on the header bolt closest to the firewall on the passenger side. Getting the old manifolds/exhaust off is the hardest part. Be sure to set aside a full weekend for the install in case you run in to problems. Also you will need O2 sensor extensions so be sure you have them. You could try www.installuniversity.com or www.ls1howto.com for installation instructions.
Also read the sticky at the top of this section: https://ls1tech.com/forums/generation-iii-external-engine/520845-mod-guide-induction-exhaust-please-read-before-posting.html. It has a detailed write-up towards the bottom.

Watch for the passenger side header as it will not come out unless you got the cat off and or the car very, very high (think lift high). Also you may need to remove the steering shaft to get it in but first try to raise the block if you have clearance issues at first. Gives about 1 1/2 inches more room to play with.

I just did LT's this past weekend. Took about 5 hours start to finish with my dad and myself. Its all about having the right tools!!
The actual removal and install is pretty straight forward and you can see what has to be removed/ put back in. We didn't have a 10mm gear wrench, but we got the rear passenger header bolt with a reg wrench 1/8th turn at a time. Didn't have to cut tabs or jack motor either. One thing that did help was putting the jack stands under the control arms in the front instead of on the subframe. It made for alot more room to move around.
If you have any questions PM me. Its still real fresh in my mind.

You could also solder up some extensions yourself, but the O2 extensions are a failsafe way to be sure nothing goes wrong. They are just plug and go. After 8-10 hours on the long tube install I didn't want to be screwing around and throw a code for the front O2's

! I've got the little box with the wires and connectors and stuff that came with the Pacesetters I ordered that you can have. I bought the Bosch O2's and have no need for the wire kit. Just pay for shipping and its yours.
I didn't use my stock bolts, I used my stage 8's... something they don't tell you is that the stage 8's are 11mm not 10mm ... therefore my deep socket set and my gear wrench set did not have said 11mm sizes... they skip right over that one... so I went and bought me both 11mm deep socket and gear wrench... worth it as I've used them more than anything else on other projects not car related as well...
my header install was a breeze... it was the rest of the install that pissed me off
getting my Y pipe lined up with the Intermediate from my GMMG was more than enough hassle than I wanted to have... and lacking a rubber mallet, I was left to beating the **** out of the pipes with my hands ... under a car on jackstands... not exactly simple...
my next install will be shocks/struts and swaybars... a breeze I assume compared to the header install by yourself
