Nope they're still called upstream & downstream with respect to the mini cats. There are 4 different part numbers for Front US, Front DS, Rear US, Rear DS. Front meaning the forward-most catalytic converter processing exhaust from cylinders 1-3

His prices are very fair; it's just an expensive upgrade.
(I ordered RXJ-242-D(1). B+ to starter, B+ to starter relay/distribution, B- to block, Block to firewall, B- to fender. All 1AWG for my Renix)

I can't watch this video at work but it looks like it may help.
If that's not the right one I promise there's a video on youtube that'll show ya how it's done.

I have never used the stuff but from what I understand ''Marvels mystery oil' is designed to free stuck lifters and such. Somebody with experience using it could chime in here.
