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).

Re: 100dba
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

Re: 100dba
Cheers Stu. Was wondering that myself as I've just removed the cat. Roll on Abingdon Phil!
