Yeah, cat and centre box will shut it right up along with even a big backbox.
Is the box designed for a petrol? It'll have a lot of sound deadening in it even if it's "big bore" because petrols are vastly louder than their diesel counterparts!
Drop the backbox off and start it, is it loud then? If so then the box is removing a lot of the noise, might need a different box, but you can also try removing other boxes.
