Why not get the phone app and get a mate to measure it for you? They arent totally accurate but will give you an idea.

Ive got one on my Bug and its not too bad but if the guy above is correct at 107db then your gonna be pushing it as most trackdays are about 100-105db im my experience mate.

Ive got the bung for it but its been mapped without so dont want use it on the day as it will prob do more harm than good. Im away in warrington until Monday afternoon so i will give oulton a ring and whizz over to get it noise tested.

Plenty of people use bungs on trackdays, all mapped without them fitted too.
