o.k. i'm looking for headers for my new ride . i like the hedman 68478 headers with the 17478 Y pipe . the question i have is do they an o2 bung on them ? i have been on hedmans web site and drew a blank . anyone know ?
well this is a first , asked a question and nobody knows . no sarcasm intended . guess i'll just get them and see for myself . if i have to i will weld in a bung on the "Y" pipe below the collector . has anyone done that ? installed an o2 sensor in that area , any problems ?
I have the shortie hedmans with the y-pipe and no, there is not a bung in the headers. I wouldnt put the 02 in the y-pipe, Id rather have it closer like in the collector.

I have the same set up on my 91 rs. I had an O2 bung welded to the y pipe just down from the collector. This is what the folks at hedman recommended. Set up works just fine...

Same setup here. I did install a heated O2 sensor for fear that the stock one would be too far away to stay at temp. Ran it for a few hundred miles with the stock, unheated sensor in. Ran OK but warmup is definitely faster with the heated sensor.
thanks for the response , i'll put the bung in just below the collector . i knew someone on this forum had to have run across this problem . will be ordering them this next week . thanks .
