Bank 1 vs bank 2? P0420

[RGenny12]

Hey yall, it's been a whe but I'm back in another genesis! 2009 4.6 this time. Miss my R spec bit this one's nice too, I just love these cars.

Anyway, I popped for a p0420 code, which is for bank 1, I just can't find a firing order or any info detailing which is which, I'm assuming 1 is passenger? The car runs fine so I'm gonna try the upstream 02 and go from there.

Also, I noticed a bit of delamination of the leather on the dash, otherwise it's in great shape and I got a hell of a deal on it so I don't mind putting money into it. Any ideas for a fix on this one? Most upholstery shops won't touch it. Thanks!

The 2009 V8 Tau engine firing order, according to chapter 2 "Engine Mechanical" page 1 table is:
1-2-7-8-4-5-6-3

Bank 1 is the passenger side.

I think the cylinder numbering is
1-3-5-7 front-to-back on the passenger side,
2-4-6-8 front-to-back on the driver side.
The factory service manual doesn't actually show this info - at least I haven't found it.

Actually, after much digging I was able to find it in another thread. I thought passenger side is generally bank 1 on most cars from what I've experienced, I appreciate it!!
