chavs crave for that sound 
is it de-catted? centre section removed?
if so it will make that sound, ad the de-cat or middle box to reduce the popping sound!

exhaust isnt gas tight somewhere, i get this on mine, but i have got the centre section removed, and all the egr shite is gone too, i think this makes it fizz pop and bang when coming off full throttle

I was thinking that it wasn't lubed somewhere but decat and middle box may also play a part .
hope ya get it sorted.
