Install Hooker LTs on 2002?? I'd like to install a set of Hooker LTs on my 02 SS this winter, but I see that the headers are for 98-99s.
Sounds like the main difference lies in AIR and EGR systems. What do I need to make these headers work on my 02? Do I need AIR & EGR tubes, or do I need AIR & EGR blockoff plates, or some combination of both?
I apologize if this has already been posted; if it was, I didn't see it. I'm guessing I'm the only dummy asking this question <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
Also, does anyone know where I can find some detailed instructions for installing the LTs? I checked installuniversity.com, but I couldn't find anything.
TIA

Re: Install Hooker LTs on 2002?? from what i've heard, the instructions that come with the headers are very good and very easy to follow. as for the a.i.r system, you have to either buy a new set of a.i.r. tubes or bend your existing ones so taht they will fit on the headers correctly. I'm not sure for the EGR tho, i'm kinda wondering that myself <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> , i'm gettin these headers for my 2001 z28 in about a month.
Re: Install Hooker LTs on 2002?? The '01s and '02s do not have EGR, so you will have to run a EGR block off plate. If you are going to run an off road pipe with no cats, you might as well do away with the AIR tubes as well, as their only function is to supply an air supply to the cats. As far as install, they are pretty easy, just have to remove the steering shaft for the driver side header, and both go in from the botom. You will also have to modify the driver side heat shield that covers the fuel lines for O2 sensor clearance. (You'll see where when you get them on). They were pretty easy to install, just gotta get the car up HIGH.
Re: Install Hooker LTs on 2002?? Just like to add on top of what the previous post mentioned.
If you do want to get rid of the AIR system you can, however in some cases it may throw an SES light. If you have LS1 edit you can delete this with no problems. If you do stick with the AIR system then I highly suggest doing the AIR restrictor mod. Basically there are plates that have about a 3/16" of hole drilled throught the center that restricts a lot of air from flowing through the check valves. If you don't you could possibly burn up your check valves and you will here a fluttering/ticking sound.
You can buy a set of 98-99 AIR tubes from your GM Dealership or you can buy some used ones in the classifieds sections like I did for like $30-$40. This way you do not have to bend your tubes that is on your car right now. You can just bolt them right up.
Also on the driver's side header when you go to install it, after removing the steering shaft, you must also remove the oil diverter plate that sits right on top on the oil filter. Make installation a breeze.
I did mine in the garage and the front wheels were on a set of regular sized ramps had plenty of room to play around.
Hope this helps. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

Re: Install Hooker LTs on 2002?? Thanks for the info, guys!!
I'm planning on running true duals without cats; with that in mind, it sounds like I wouldn't need the AIR system.
So... it sounds like I would need an EGR blockoff plate and two AIR blockoff plates for the headers. Does that sound about right?
Also, will it hurt to throw the SES light (ie, knock retard, etc)? Is there anyway to get rid of it short of LS1Edit? I plan on throwing a cam in next year and having some professional tuning done then.

Re: Install Hooker LTs on 2002?? 02bluess,
As the others have mentioned, your '02 does not have EGR so you will need a blockoff plate for that. The 98-99 AIR tubes are different as well, so you have two choices. Either do away with the AIR tubes altogether or retrofit to the 98-99 setup. If you do the latter then I would recommend picking up the driver side and passenger side AIR tubes from a 98-99. Part numbers are: 12559188 and 12559189. I got mine from Thunder Racing. I chose to keep my AIR functional to avoid problems with the new OBDII emissions testing that we have here in WA.
Like darkhalf mentioned, you should also do the AIR restrictor plates if you keep the AIR intact. I got mine from www.paceparts.com, but you can make your own. You'll need 4 AIR gaskets and some sheet metal. Use the gasket as a template for cutting the sheet metal (ends up looking like a small diamond shape) and drilling holes for the attach bolts. Then drill a 3/16" hole in the center. This 3/16" hole restricts the flow through the AIR tube and helps spare your check valves.
Beyond that, you'll also want a pair of O2 simms to replace the rear O2 sensors. These are required if you don't run cats (otherwise you set an SES light), but are also a good idea if you do run cats. With LT's the cats are pushed far enough back that the rear O2's may not heat up properly and give you problems. Running O2 simms in place of the rears will alleviate that. You can also reuse the rear O2 sensors (with their longer pigtails) in the front since the front O2's will now be further back in the header collector.

Re: Install Hooker LTs on 2002?? So if I were to install hookers on a 01 ls1 with no cats and sans air system, I would need the egr block off and air block off plates? Where would I get these? PN? Or could I fabricate these plates with the sheet metal direction described above?

Re: Install Hooker LTs on 2002?? I just bent the passenger side AIR tube (rotated flange ~90 degrees) and it fit up perfect. The drivers side took a little more twisting and bending and a little piece of rubber hose spliced on behind the check valve. I just happened to have the piece of hose I cut off the AIR pump to air filter from when I installed the little K&N that came with my lid. I made the EGR block-off out of some 1/8" steel I had laying around. It sounds like I should be making up some restrictors for the air tubes - I guess that all goes away when I get LS1 edit this winter.

Re: Install Hooker LTs on 2002?? Does anyone have any pictures of this? I dont understand what I need to do with the air and egr. I am going to install Hooker LTs on a 01 and trying to see what I need to do to install them, how long does it take to install them.
