theres 3 o2 sensors holes on this thing.
2 on the main pipe..
1 on the pipe leading up to the manifold.

my 95 has 2 o2 sensors....whats the deal?

btw i bought this ypipe used from a cali spec 99.

im buying the hardware tomorrow..but this extra o2 sensors has me stuck.....is there a plug for it or something?

 

ahh...went to maximadriver.
and found out i need a plug for that third o2 sensor hole....

is stillen the only place to get it?..
or can i go to a sears or something and get it?

 

I'm buying a 2 piece stillen y-pipe used this week and I'm having similar questions. It is off of a 99 maxima, so I need that extra piece for my 97 Cali spec. I think all that is needed in your case are the gaskets, plug, and possibly some new bolts. Where are you located? If you are in Southern California, maybe we can do the install together.

 

you should be able to get a plug at home depot or other similar store

 

Just take one piece with you to the hardware store and see what kind of metric short bolt will go in there. Or you could go to muffler shop and have them weld in a plug.

yeah im in socal..los angeles. i figure this whole thing out..its not too bad..but since i got the ypipe used with no hardware i was asked out. but im going to pick up a piece i need today.

 

Seems like the thread size is an 18mm with 1.5mm pitch, it is the same size as most spark plugs. I would get one from a bolt company (look in the yellow pages) or an auto parts store with specialty bolts, it would run about $.50 from a bolt company about $2.00 from an automotive part store.
