T350C Exhaust noise levels

[Captain's log]

Does anyone know how many decibels a T350 kicks out, as i'm thinking of doing a track day soon? At Goodwood in my trusty Chimaera they asked me to rev it to 75% of it's red line to check it's noise. Does that mean i would need to rev the T350 up to 6000rpm for a similar noise test?

Should be under 98 dba (without pops and bangs) if the red line isn't obvious say it starts at 6500, that's realistic.

Quick question - Is the ACT box approved by the factory?

Thanks 2 Sheds, i'll get it tested soon.

Mine tested 97.3dB @4000 RPM at Castle Combe last June.
Tested 104dB @5000 RPM at Oulton in August, however one of the catalytic converter canisters cracked at Oulton so I am assuming that is why it was so much noiser there.
