a drummer exhaust baffle?

I bought my XB12R (2004 model) last week and decided to go down to the coast this week end.
The bike has the race ECM, K&N filter and a drummer exhaust, with a fitted baffle to make it a bit more PC...

However somewhere on Devil's Dyke the bugger vibrated out and I scared little children in Brighton! I love the snap crackle and pop when closing the throttle but it is REALLY loud now...

Does anyone know where I can get another one?

Web search did not land anything...

Thanks for your help

I understand there's one alongside the road near the Devil's Dyke.
