for the upcoming track days I'll be putting a standard exhaust on.

I wondered, from people's general experience whether to hit 100 db (Castle coombe for example) I'd also need the CAT in?  Car is Supercharged as I expect that adds to the noise?

My rough guess is that I don't need it (as the club cat wouldn't exist, or be used more often).

Nope, you won't need a cat. I've never used it yet for a track day.

Mine is the same as yours (3.5,310) and it was 93db at Combe last month at 4,500 rpm.
I think from memory it was 98db at Brands when tested at 5,250 rpm so you should be sweet without the cat in.

Cheers,
Stu

Thanks Stu, that's perfect!

Cheers Stu. Was wondering that myself as I've just removed the cat. Roll on Abingdon Phil!
