I just got my heman shorties from Jet-Hot, and I think that I got the wrong part. The Y-pipe doesn't look right at all. I can barely make out a part number stamped on the flanges that looks like 69481 (for a gm truck) instead of 68481. Can someone confirm that I should only have an O2 bung on the drivers side? If anyone has pics of what the 68481's should look like that would help too. Thanks.

Car specs would help...

But generally speaking the 3rd gen f-bodies do only have one O2 sensor in the drivers side manifold/header...

fresh from jet hot

Look the same as mine them are right!

Except those aren't his, those are someone else's pictured for reference. Yes, there should only be 1 o2 bung and its on the drivers side.

Opps!

Thanks guys. I was already pretty sure, but that is definitly a different Y-pipe. KagA152, did you have the AIR tubes removed, or did you go with the non-smog headers?

Oh yeah, it's an '86 LG4 Firebird.

i bought them off a friend, so im not sure, but judging by the weld job on the o2 bung and y pipe joint, im going to say they didnt have air tubes cause theyre still nice and smooth up there

The Headmans don't have an 02 bung. you'll have to weld one in. I put mine in the short piece of the ypipe on the drivers side. That way the coating on the headers wont rust from the grinding/welding. Only the small piece of the y pipe will. Once you scratch the coating, moisture gets under there and rusts the whole piece.
