s3nt3nc3d Yeah...my upstream sensors weren't anywhere near the cat

tangofox007 I suspect that a closer examination on your part will reveal that the upstream oxygen sensors are located a bit further "upstream."

No pre-cat O2 sensors for aftermarket catalytic converter?

Bought a Bosal catalytic converter to replace my original that was throwing code P0420 (yes I already replaced all 4 O2 sensors) and new one doesn't have pre-cat sensor ports or even a neck for me to weld in. Anyone have this problem or insight as its clearly not going to pass inspection as pre-cat O2 sensor codes will trigger. Part No. 079-3108. Inspections already up trying to get done ASAP, guessing have to order a different cat so any recommendations?
