Do the Jdm Itr Cats come with an o2 sensor bung? I have a 97 gsr and I was wondering if the o2 sensor will fit into the thread in the cat? I've had different responses saying that the itr cats have a heat sensor bung where the thread is too small to fit the stock o2 sensor in...

 

I have a jdm ctr cat and there is no bung for the o2 sensor it is on the end of the exhuast manifold. I could be wrong but i think they are the same cat.
