You want to know out of interest or need official paperwork?

Alternatively ride up to Brands Hatch and get them to measure it
If you have a road legal exhaust with the catalytic converter still attached then you should be fine regardless of wether the baffles are in or not.
My GSR had no cat and did 100db with baffles and 102db without. I could ride brands without baffles. 
Not wanting to hijack but i am in similar situation regarding exhaust volume . My bike is due its first mot shortly and i have an arrow full exhaust fitted which has no baffle along with a power commander fuel and ignition module ,it obviously won’t pass an mot so i need a volume friendly mot center. Any known pm me please ??
Mine passed mot. No cat, no baffle. Go to an independent. Take baffles in rucksack
