Tullet exhaust noise

Anyone got any experience of full Tullet exhausts on the noise level of a 240PP.
I desperately do not want the noise police to stop me enjoying Goodwood and alike.
No other engine mods at present, but likely to follow.
Thanks

Goodwood has very strict noise levels IIRC, Doubt anything other than the std exhaust will pass…

As it happened, this last weekend I was one of only a couple on standard exhausts, but only 3 cars failed out of 30. I just don’t want to be a member of their pit lane voyeur party.
