Does anyone know how noisy a JP sports exhaust is when fitted to an otherwise standard T350?

Being new to TVR ownership my girlfriend has kindly bought me a MotorSport Vision trackday and I'm trying to find out if the car would pass the noise regulations (most tracks are 105db).

I love the sound from the JP exhaust and would rather leave it on, but I do have the option of temporarily switching to a standard exhaust at my next service.

Thanks

Mine was 103db (with standard cats) at the standard track tests at an angle stood near the exhaust at 2/3rd max rpm. It's an exponentially rising scale as you may know, so you should be fine unless it's also decatted.

Anyone else out there with a JP exhaust they've noise tested for a track?
