there is a o2 hole for a sensor on your header. If your running F22 than thats where the o2 sensor goes. If its h22, then you should have bought a h22 header with a downpipe and o2 hole in it.

ok for the header i bought it says in the description no o2 sensor if lets say there isnt is it bad to not have it in????

That header shows a 02 sensor bung on the #2 runner. As long as you have the F22 that should bolt up as your typical generic header.

Now that I read it, the test pipe(catilytic converter replacement section of pipe) has no 02 bung so as long as you dont have emissions laws in your area for your year cb then you are fine, just cut the wires out and roll with it.

you must have an o2 sensor in it, otherwise your car power, gas mileage etc will go crazy. And i can see a hole in a picture. Cobalt's right. 2nd "pipe" from the left has a slot for o2 sensor. I dont understand why they said it doesnt.

ight no problem thank you guys i was searching alot and couldnt find anything on it this was my second option but thanks now some 1 knows in the future

Keep in mind that the F22A6 (at least mine) has the O2 sensor on the flex pipe ahead of the converter, not on the manifold like the F22A1 in my LX's. If you have an LX, you should have the header with the port.

I edited my post, in the CB and all cars since the early 90's/late 80's they have 2-4 02 sensors. the CB and all other 4 cylinders(eccept maybe subies, I cant remember the last time I worked on one) have two, an upstream which affects your AFR and a down stream that checks your cat's efficiency. With the Test Pipe on there it is also removing the second 02 sensor since you no longer need it and it is just more production cost to drill a hole and weld a bung.

so wat does that mean brake it down???
