Secondary cat is before the side long silencer.

I wonder if the BMW cars using this engine had 4 cats as well? Seems a curious setup with two back to back either bank.

Viper, given that squeezing 4 gallons (AM V12) into a thimble (V8 engine bay) along with all it's additional cooling etc is the 4 cat solution not more related to packaging? 4 little un's instead of 2 bigger un's?

Hence the sensor being over the pair of them?

Meant as a question as much as anything else.

Everyone loves a Morgan. Even me, unless it's broken again.

Alistair.
You could have a point but I’m not aware of any large lumpy V engine with just one per side. Could be wrong of course.

Sensors are always pre and post. Would be pointless putting a sensor after the first thought that’s effectively what I have on the AM now.

I’m trying to build up enthusiasm to take the aero apart and send the cats off atm.

I need to have a really bored few days I think

I don't know how emissions inspections work in the UK, but here in the US removing catalytic converters is verboten. Tampering with any of the required emissions equipment subjects the owner to fines and suspension of the vehicle's registration. Companies that supply emissions work-arounds are receiving big fines Like this...
