What do I need to install these ARH headers?
12" O2 extensions? or 24"?
Spark plug boot covers.
What else? New flange gaskets?
These are supposed to come with the hardware for the slip flanges.
Don't know your mileage ?? I installed new plugs and wires with a good set of boot covers, great time to change motor mounts, I replaced my starter with a new one, (didn't have to) installed a tunnel plate, made sure all my wiring routed up so not to be near the headers at all, double nutted my collector bolts, I pulled my valve covers to check for rocker arm failure, made suremy starter wiring and air conditioning hose was out of the way. I wrapped my AC hose to be safe, three years no issues. while I was under the car replaced the fuel filter. I sure I forgot something ?? Oh I replaced the front O2 sensers !! I reused the stock header bolts !!
O2 extensions. Got mine in couple days-Call and give them your info....
GM Ex. manifold gaskets -Call Gene, he knows what you need- http://www.cultragfactoryparts.com/
It's a good time for general PM if you haven't done it in a while. Easier access to some things. Here's what I did when I installed my LG Longtubes, and again when I removed them for clutch work.

Plugs
Wires
Wire thermal covers
New gaskets (both on manifold and various flanges)
Zip ties and heat shielding to keep wires/plugs away
You can run the rears in the front with a harness adapter, you would need the shorter adapter harness as the wires are longer. LG and Dynotech go with the rear up front as the primaries are longer and the rear sensor warms up quicker.
I've already tuned out my rear o2 sensors. Figuring the 12" o2 extensions are my best method now. Hoping I only need 12". Can anyone confirm for me? These are ARH headers. Want to buy them tonight, in case my headers get here fast. Want to be ready
If you have extra, tie strap them and be sure they don't rub or touch the hearers or ex pipes..I used aluminum foil as a cover and tie strapped them back out of the way...

12" is long enough. I did the 1 3/4" arh this week. What size are you installing?
But i moved my rear O2s to the front and closed off the rear bung holes.
Forum member mikeventh alerted me to the racetronix rear to front harness and I am returning my 12" black 4pin extensions.
The "thanks" was in error.
Thanks!!! I got the extensions! Are the rears really more effective at doing their job on my ARH headers? Mine are 1 3/4" primaries. 3" collectors!

I was told that the rear O2 sensors heat up faster. Apparently a lot of tunes eliminate the rear readings anyway. I am rather uninformed on the whole O2 design thing.
I too have the 1 3/4" headers, catted mid-pipe and the Ti exhaust. It has an amazing sound.
Hope that is somewhat useful.

You can run the rears in the front and rear, if you do not want or can not program the rears out due to emissions testing. Racetronix sold the adapter harness.

Not THAT uninformed. I have the adapter harness from Racetronix.

Bought headers, want advice on what to order?
