I too, am joining the "Solo Family". Got the HFCs last week.
I am going to use the factory exhaust and....I am buying new O2 sensors.
I plan to leave the original sensors in the stock cats.
And this brings me to something that I can share with you guys.

According to my research, the "upstream" sensors are originally supplied by Denso.

And the "downstream" sensors are originally supplied by Bosch.

I work for an authorized distributor of both manufacturers, and each one claims
one of the sensor positions as "OE Supplier".

Weird, huh? Well, stranger things have happened....

And while we are here, the part numbers are.......

"Upstream" Denso part number 234-4669
"Downstream" Bosch part number 15698 (same as F 00E 262 994)
