Whenever you think you have the car jacked up high enough - raise it another click on the jackstands. The rear header bolt on the driver's side is a PIA. If you have a swivel socket or like a 1/4" drive it makes it a lot easier.

if your headers have the dual bungs for the O2 sensor and the wide band, make sure if you are not running the wide band, that the O2 sensor goes in the front one, not the rear one. You will know it fit because the O2 sensor will have more than a fingers width clearance. My headers came backwards and it was a PITA to fix it once I had the headers all bolted up.

Make sure your local dealer has at least one 02 sensor in stock,there is a good chance one will get fubar when removing them. Put a small amount of anti seize on the 02 threads when re installing.

I took a sharpie and put a little arrow next to where the dip stick went in. When I intially looked at it I said..."easy, right in front of the starter"....but because everyone mentioned what a PITA it was to find after it was out I decided to put a mark anyway. That saved my butt! Even with the mark you'll still have a little issue with getting back in properly but at least you'll know where it goes. This is a must IMO. Put a mark next to where it goes!

I know this sounds stupid but no one ever mentioned that the dip stick is bolted to the block right around the spark plugs. I assumed it was underneath and took me a little to figure out it was unbolted from up top...not underneath.

Other than the dip stick, the only other real issue I had was getting the steering knuckle back on to the gear box. Trick is to make sure to spread apart the clamp that connects it to the gearbox. I had to hold the steering knuckle up against the side of the car while someone else used a screwdriver and hammer to try to bend the clamp out a little. Goes back on pretty easy once you do that. That was on a set of ARH headers though. You may not have to take the knuckle off for KOOKS. That cost me a good 30-45 min to deal with. If you can get the driver's side in with the steering in tack you'll save some time but don't beat up your headers trying to force it up there. That ceramic coating is beatuy and you don't want to scratch it up. Take off the knuckle if needed.

If you can warm the car up, then get it up on stands or a lift, immedially break loose the O2 sensors. The extra heat in the exhaust should help get them loose.

When you put the rear O2 sensors back in, go a head and un-plug them. Otherwise the wires get all twisted up. The plugs have a safety latch type thing. Slight pain to get off. I think I just cut them and didn't put the safety thing back on. It's a little piece of plastic so easy enough to cut.

Make sure to use Anti-seeze on your bolts and O2 sensor threads when putting them back in. Also, I took the header bolts and touched them up on the the wire wheel of my bench grinder. Just takes the top layer of junk off so they'll go in easier.

Edit: post up if you have to take the steering knuckle off or not. I didn't put my KOOKS on because I got a package deal to install with purchase. If you don't have to take the knuckle off that would definatley give KOOKS a slight advantage over ARH for those trying to decide on which one to buy.

#1 disconnect the negative battery cable on the battery as to not short out the exhaust on the starter post !

Use OEM header gaskets, not Kooks gaskets.

ditto. Buy two extra o2 sensors. If you don't need them take them back. Disconnect the battery cable and be careful not to hit the headers on your spark plugs if you dont fully remove them. Install is easy though. Buy a tirque wrench if you dont have one to torque the bolts down to factory specs. I didnt put my o2 sensors back in because they were bypassed.

Also, when taking out the factory O2 sensors, if they get tight coming out, then turn them back in and go back and forth until they are out. 97 times out of a hundred you can get them out this way without needing to replace them. Then as has been mentioned, use anti-sieze when you reinstall them.

Also use anti-sieze on the header bolts. Many people use lock-tite, but you can screw up the threads if you take them out and in again. There is still some factory lock-tite inside the threads in the head, adding more will just make it more difficult and could cause problems down the road.

We always use GM exhaust gaskets and Kooks bolts with anti-sieze.

Feel free to call, email, or PM us anytime!

I managed to get the one O2 sensor off that was stubborn by using wd40 and an open ended wrench. I got it to move a bit, sprayed with wd40, wiggled it and kept going. Eventually worked its way out. Had to clean up the threads quite a bit, but it worked.

Other than disconnecting the steering shaft from the rack (which is easy), in order to slide the header in, and then putting it back when I was done, I found the Kooks longtube install to be very very smooth sailing on my car. No problems or issues at all, everything fits great.
