I want a header that I can put my O2 sensor in without having to get a bung adapter and then weld it in. I don't want AIR but now it seems like I don't have a choice. I am trying to get a true 3" system to match up to my hooker cat-back. I will have to cut off the reducer on the I-pipe but thats not a real big deal. Any thoughts?

Hooker 2460, shorties, Note 92 says, "This header is equipped with a fitting to accept the stock oxygen sensor."

Note 2 says, "Available with fittings to accommodate air injection manifold. Add a 0 in front of the part number when ordering."

You'll have to have a y-pipe fabricated.

 

What about the hedman or an SLP y-pipe. Will either of these work?

 

SLP sells a series of different y-pipes. I could get the one for the L98 cars (3" I think) but I am not sure if they will accept the ball flange on the end of the hooker ones.

 

SLP y-pipes fit either stock manifolds or their headers. Hedman's y-pipe fits Hedman hedders only. Nobody makes a y-pipe that fits the Hookers directly.

The 2460's don't have a ball flange (2055's do).

 

I have decided to go with the coated flowtechs. They have smaller primaries than I would like but they come with a y-pipe and everything I am looking for. Plus This is on a 305 that will probably only see 300hp after numerous mods down the road, so the 1.5 primaries should sufice.
