Oh, so that's why that F-Type was so far behind you on that drive. Here I was just thinking he couldn't keep up with a modded ST-R!!! FYI, stock setup with cats doesn't smell like a bed of roses either.
It's still inspiring work, anyway!

No CEL's with the o2's setup this way...
In my past experience of trying to eliminate p0420-cat-efficiency codes due to high-flow-cats/cat-deletes, the 'sparkplug defouler' trick at the secondary o2 would work well. A reduction of exhaust flow directly over the sensor was enough to fool that particular emissions-only monitor...
Recently, I've found that merely having it plugged in and reading free-air, is enough to avoid throwing any p0420 style cat efficency codes, or any other code, so for now, that's how I've left it, and it's been fine for the past 5 months. I would consider threading them back in along with a defouler/spacer, to have it looking proper undearneath, come inspection time.
It's not uncommon in aftermarket tunes/programmers, to have the option to disable the secondary o2's altogether. Will not effect engine operation in any way, and will test perfectly fine on the latest obd2-based emissions testing procedures... I'm fairly certain eurocharged can disable my secondary o2's if I so specify the next tune around...

Great video thanks ! Cool turn out with lots of new and old but I must say not very old ,
Our local club is mainly 60s to 90s jags with very few from this centery bar a few .
Grate move on the catch can I just done the same . You'll be surprised at how much oil was being sucked in the intakes before , the can will only do it good . Well done .

Recently put the cats back on, installed two new magnaflow 2.5 high flow cats,
The axle-back section was redone with all new piping; deleted the mufflers, put resonators in their place, and reused the tips from my Mina gallery mufflers...
Here are some sound clips with some WOT pulls...

Doesn't that car just stand out on its own even in mixed company?
That is a stunning and very well finished car. A subtle and very classy look.
From the clear side indicator lenses, to the body coloured bumper inserts to the oh so subtle badging. When something is that good you don't need any overstatement.
Top marks and I would be very happy to live with that.
