Where is my O2 Sensor

[HTN]

I've been researching quite a bit before attempting to replace o2 sensor myself.

Code is P0135 Bank 1 Sensor 1.
Can anyone identify if this is the correct one? Just ordered Denso part #4093.
Please help.
Thanks

Think i had two on mine when i replaced them.

mine are aftermarket headers and was at the end of the header just after all 3 chambers merge.

There are 4 total.
I'm just hoping that this is the correct Bank 1 Sensor 1.
My searches here led me to Rear Primary Before Cats.
I know the pic looks confusing. I sure am.

Yes there are 4. One in each exhaust collector (sensor 1) and one in each Cat (sensor 2). Bank one sensor one would be the rear bank in the exhaust collector. Hard to tell from the pic but that is the correct location. In the pic from the Cat on the right, the pipe should make a 180 degree turn and then meet up with the collector. That is where it would be, where the three pipes collect in to one.

Thanks for the confirmation.
Got the new one in and no more light. Lets hope it'll stay that way.
