I just got some MAC headers and there is no spot to screw in the O2 sensors. I had bbk's on there and the O2 sensor screwed in near the end of them. Where can i put the new O2 sensor ? The new headers arent as long as the BBK's so they dont reach the other pipe, so i'm gonna have to get an extension pipe or something, the guy who's helpin me said he can weld one so i'm not too woried about that.
What are my options to install these O2 sensors ?

HMMM........Can i drill a hole and weld a thread of some sort in there so i can screw in the O2 sensor ?

i guess you can do that, as long as you can still hook them up to the wires so they work

So you bought shorties to replace long tubes? Thats what im gathering from this.

If you bought shorties you should have gotten the shortie header H-pipe also, thats where the 02's screw in on the shortie header set up, on the H-pipe.

like 88stangaruu said, your exhaust setup will depend on where the O2's are. Since there are none on your headers, you can check your H or Xpipe to see if there are any there.
If not, you'll have to have some bungs welded in. You could find a junk exhaust & cut the ones out of it then weld them in yours.

if you want to do it the hard way you can weld in a bung.

I'm not gonna be doin any of the welding myself, the guy who is helpin me do it can weld, he said he can weld somethin up for me. But i think i'll just get a H pipe, if funds are applicale.
