    A lift or jackstands, assortment of hand tools, liquid wrench, a buddy, and a desire to bleed from the knuckles. And some extra time.

    what's a liquid wrench? and also you might want to get replacement header gaskets, cuz the ones that come with headers usually suck. you'll need 02 extensions and simulators if you don't already know that...

    Liquid wrench AKA penetrating oil. Used to break through rust. I highly recommend it on EVERY bolt that you will be touching. A little time now will save from breaking bolts later. And yes, new OE metal gaskets are a good idea.

    excellent, i'll definitely get both of those. hopefully i can get enough cash to do my install in june. ss zoso ss's shop doesn't look under the car apparently, so i think i might go with the ory... i'm a lil worried about rasp tho.

    i couldn't imagine not useing a lift to do these

    i had a lift and it went smooth

    and i had air tools which made getting the old crap off alot easier and faster

    did everything on mine in under 4 hours

    you'll need someone with small arms since i can't get mine back there it was a pita for my buddy even to get the bolts out for the manifolds

    You spoiled turd...I did mine in the driveway on my back with jackstands, and I didn't feel like using the air compressor either. That's how a lot of us do it. Do whatcha can with whatcha got. It wasn't THAT bad though.

    He used a sawzall more than I thought would be needed. I would only use a sawzall to cut the catback or y-pipe. The hardest part is getting the old stuff out. Once you've done that, the battle is half-way over. Then once you get the headers in, you're practically done.

    A lift for a header install is like finding diamonds in your backyard...

    Gaskets are included, but you have to buy extensions seperately. Mine were $17 each. You can buy o2 sims for the rears, but they are not cheap and have to be replaced as they go out. Best bet is to get a tune or someone that can tune for you to delete the rear o2 sensor so it doesn't set a code.

    Personally, I would buy aftermarket extensions and not use the spliced ones that come with the headers. Extensions are pretty cheap and I've never been a fan of cutting wires if I don't have to. Might want to get some gaskets for the a.i.r. system. I forget if mine were ok or not. I bought gaskets anyhow because they're cheap. I passed on the liquid wrench and went the sawzall route. None of my stock exhaust will ever go back on and it's much faster just to cut the shit out of there and be done with it. If you're doing it on jack stands make sure your jack will get the car up high enough. It has to be really high and when I say really high I actually mean dangerously high.

    It hasn't happened to me personally, but several people have posted problems with having to replace them on LS1 forums as they set codes when they get older.

    Here's a good excerpt from http://www.ls1tech.com/forums/showth...hlight=o2+sims . Several people there had the SES light problem after o2 sims failed to work.

    Rear O2 sensors - Emissions controll "tattler". Reads the exhaust gas after the cats, compares content to that of the front O2 sensors, makes sure cats are doing their job.


    Removing the rear O2's is a must when doing headers. Even if cats and rest of equipment is used, SES light will still come on most of the time due to abnormal readings.

    Solutions:
    Buy O2 simulators - these plug into the harness and simulate a functioning cat. These have been known to STILL not prevent the SES light after exhaust work.
    Have Rear O2's tuned out - better option, usually cheaper than buying O2 sims, guaranteed to stop SES light.

    Best Option - Have REAR O2's, EGR, and AIR codes tuned out at same times, even if you wish to keep EGR/AIR. Any speedshop with LS1edit/HPtuners can do this. A friend who has a multiple car copy can as well. 2K2WS6TA has noted that the new Predator can supossedly delete the codes (per their website), but I'm not sure. Most handheld programmers can "read" the code, then "clear it", but this is not "deleting". When a code is "cleared", the SES light only goes away, but comes back when the car is turned off and re-started. If anyone has any info on this, post up!

    Cost:
    You can call around to a local shop and ask. I paid $75 at MTI, and should expect it to cost around that much. Some shops might even do it for free hoping to strike up some business. Go to LS1tech.com, click the top right button, and search sponsers by zip code and distance. You can also do a mail order if you don't have access to it. You just ship them your PCM, they edit it, and ship it back.

    i didn't read those but that's not what I wanna hear. I won't be putting a lot of miles are the car for the next couple years. Only a DD in the summer, so hopefully the 02 sims can hold until i get more boltons and a full tune.
