THere are only two inserts....at triple fin, which comes in the bov already and a round centered one. The purple one with round center makes it quieter. THe gold triple fin is the same as the silver stock one....Just different color. So no there isnt one that makes it louder then it comes out of the box.

turn up the boost to make it louder
