360 la headers & straight pipe

On our dart we have 360 la , headers , straight 2.5 all the way out the back . It's not very loud . At idle it's quiet even . If we slam on gas it pretty loud but not Like we want. Not at all like others guys with 318/340/360s I see at hangs. I want our car obnoxiously loud . We had glass packs on it and took them off
