o2 sensor swap problems

[deity]

heres my problem. on my b20z i have a gsr stock exhaust header. it does not have an o2 sensor bung.

theres is also a header to cat clearence issue that i need a exhaust shop to fab up when i get this swap done.

would putting an o2 sensor bung into that extra extension ( which is before the cat ) be a good place to put the o2 sensor?

i figure i can kill two birds with one stone with getting a bung welded in there while its at the shop.

Your primary o2 should be before the cat.

odd, my gsr has the o2 in runner #4

Primmarys before the cat. Secondarys after the cat. so that should be good but you need one behind the cat.
