Any recommendations for placement of the 02 sensor for a wideband with stock cats?

 

hey dave isn't there room to weld another bung next to the stock o2 sensor

 

I don't have the cats on me, they are at the shop....I thought there would be room in the cat itself as well....just wanted to confirm. So it can definitely be put into the stock cat then? And you say next to the stock 02 sensor?

 

Anybody? I have about 30 more min max to find out for sure

 

hope this helps...
i just had a bung welded on the the cat right next to the attachment to the headers. I peeled & cut some of the aluminium shielding off & welded it on. From what i've read you want to put it before the cat elements. More accurate readings.
