How many decibel (dB) is a T350 with JP?

Hi all
Thinking of doing a track day and it seems these 'track day' websites seem to plastered with sound warnings, Im used too doing trackdays in various other cars but can't help thinking the Tiv is too loud, anyone been to brands hatch recently with my setup and not been black flagged?

My Tam with JP is 108db so expect yours to be similar

So I rekon no TD's with out changing back to standard and they will need to be 105db days. I expect to need extra TD cans to get under 100db

Standard JP is way too loud for track days. You will need the new JP full system that ACT are now selling (~£750 I think) instead that I have fitted if you want to track the car, as I don't believe there are track day silencers for the standard JP due to the rolled tips.

I am currently looking to swap my JP full system (bigger bore centre pipes + larger backbox) as I am now not planning to track the car, and whilst my JP full system does sound great I do miss the raucousness of the standard JP.

If you are interested in my full system (from the cats) in exchange for your standard JP backbox + some cash then do let me know and I am sure we can come to a deal.

Out of interest - what's a standard T350?

Around 97-98 Decibels, same as a Chimaera/Griffith/Tamora.

Edited to add: of course this varies depending on distance to exhaust, revs, climatic conditions, but the normal trackday readings are this.
