What do you need to buy besides the LT headers? Do U need new header bolts, new y-pipe or stock OK, extended O2 sensor, etc.? This is my first time, so all help is appreciated

 

Headers come with bolts, gaskets, a roll of wire and butt splices for the O2's.

Y pipe comes with clamps.

I ordered from Maryland Speed, they have an option box when you order that allows you to select O2 extensions with plugs, 24" for $36.

I ordered from them because you click on headers and all the options are right there, you don't have to search the whole site for the other stuff.

 

Do Not use the gaskets and wire that come with the headers.

Get.
GM stock Gaskets.
O2 Sims.
2-24 O2 extension.
I used Stage 8 Header Bolts.
10mm ratchet wrench to remove stock header bolts.
11mm ratchet wrench if using Stage 8 Bolts.
Might want to replace your plugs and wires during the install.

 

Call TSP and tell them you want to put pacesetters on your car. I beleive they have the cheapest prices on them.

I just got the coated race headers, TSP O/R Y pipe, O2 extensions, TR6 plugs and MSD wires, and an EGR plug for under $700 shipped. That's everything you need to put pacesetters on your car..........except for a lift

Reuse the old gaskets and front O2 sensors and the O/R Y pipe comes with 2 band clamps for the Headers to Ypipe connection and regular U bolt clamps to assemble the Y pipe. I'm gonna get mine on with the U bolt clamps and then take it down and have it welded.

 

I got my pacesetters from ls1speed free shipping.

 

I have a question about the pacesetter's. I had them on my LT1 with the ORY and they tucked underneath really close and the damn y pipe would hit my floorboard. Does it do the same thing on the LS1's?

 

Yep, the pacesetter Y pipe has flats on the top but they come straight off the header, up high enough to hit the floor. I cut mine loose and welded it on the header at an angle.

 

Why wouldnt you use the stock wire that comes with the headers?

 

because you have to cut and splice 4 wires per side. It's easier just to plug in a premade extension.

 

yeah, you could make your own 02 extensions with the wire that comes with the kit......but don't use the walmart but connectors. Do it the right way and solder the connections.

Or, get some O2 sensor extensions and be done with it.

 

If you are installing these your self, get the arp header studs and save your self a big headache. Also if you have high mileage on your car I would recommend getting a new set of gm metal header gaskets as well. As far as the wires with the pace setters if you can solder and take your time you will save some money on the extentions. either way if you get the studs or us the bolts they come with do not forget to ANTISEIZE THE BOLTS !!!!

 

Appreciate the input guys. Got the Pasesetter LTs Armor Coat, 2-24" extension, lock header bolts, 2 o2 simulators and ORY. Did I do a bigg no no going without cats-cop wise? In Florida by he way and setup is going on a 02 WS6 with 28K

 

If your in Florida you have nothing to worry about, Just keep out of the gas around cops.

 

Don't forget patience...you'll need lots of that...haha.

 

If the headers came with copper gaskets instead of the older paper versions, you can use those. Nothing wrong with re-using the stock ones though. Then you could sell the new copper ones.

 

and BEER!

 

you will like those stage 8 bolts. The hex wrench feature is very nice, high five.

 

i got some o2 extensions i can sell u if u need them!

 

Here is everything (i think) that I've gathered up to do my header install

Headers
ORY
spark plugs
header gaskets from GM
bosch 13111 o2's (not sure if those are the numbers, its been a while)
a couple band clamps
some anti seize for header bolts
expansion plug for egr in intake mani

I think thats it. There may be a couple things I forgot but thats the jist of it.

 

Cool, U guys got me from not knowing to having a decnet idea
