Loud noises

[Wisenatcho]

I have a trackday booked for Castle Coombe tomorrow... they have a "strict limit of 100db at 0.5 m away from the car."
I assumed my 197 would be easily within the limit as it has a standard exhaust system (minus centre silencer - yes Im aware this would solve the issue haha! but sadly I don't have it.) and no engine mods, however using an iphone app to test, it would appear its 95-99db!!!

Any advice or tips on how to make it a bit quieter before 8am tomorrow??anic:
Cheers

Not sure how anyone fails one tbh.

On my last trackday it was a 105 drive by and then 95 static and the race cars running were fine. Ferrari 458 iirc and a 450bhp Brit car
