k first off if i get soem used headers that have alittle rust on them(which i can sand blast n paint) will the rust matter to much? also there headmen headers..does headmen have a 3" Y-pipe that come with an o2 fitting?

 

I guess it might matter on if they use salt on the roads in NE. I would assume so.
Just research what type of paint you are going to use. It seems nothing works 100%, except having them coated. VHT paint isn't bad, but then again, I don't have to deal with road salt, either.
As far as the ypipe goes, you're going to have to figure out which headers they are. Do they have a ball joint flange or not? Are they shorties? I thought all the O2 sensors were in the header collector.... if not, then you might have to buy one (O2 bung) and have it welded on. The further it is from the head, the longer it will take to warm up and read accurate.

 

the headers are shorties HED-68470..and i dont think those have the o2 sensor in the collector.. but i still cant find a part number or anyhting for a Y-pipe that will fit anyone know?

 

All headers will rust unless coated. Surface rust can be blasted off and then you can prep your header the way you would like. Ceramic coating is the best way to go and far better than anything you can do in your oven at home.

 

there is a y pipe for that in jegs...cuz i was lookin at those headers but ended up goin with hooker....which will be here this weekend woohoo.....depending on which flange u have tho on it....that part numbers are 500-17470 and if it has a ball flange its 500-17478

 

ok so with those headers and the Y-pipe i will have 3"s all the way to the stock location correct? also do the headers come with the 02 sensor location already there or in the collector?

 

The 02 sensor will be in the collector. I am not sure about long tubes though. I know all short kits come with the 02 bung. The cheaper sets come with the bung but they are not pre-drilled.

 

From what I have seen here locally on my car and others with O2 sensors and headers you might want to consider getting a heated O2 sensor. Seems to be a hit or miss proposition if the O2 sensor will work correctly in headers.

When I was dataloging my car I noticed the O2 sensor was recording a little strange compared to other charts that I have seen. It was an AC Delco unit with less than 5000 miles on it and on SLP headers with the stock SLP location.

Changed to a heated AC Delco unit and now things are the way they should be. Allen

 

yea i thought most headers came with the o2 sensor in them but the guy im buyin them for said there isnt one
