do you have any exhaust mods yet? I don't know if I would just go straight to dumps. with my offroad h and a/t catback, I had the carpet, and everything out of the trunk, and it was alot louder, with the seats down. definately made me think about my neighbors. but I want dumps as well. try mustang exhaust, they should have something. the sound would be more centered under the car vs. rear exit. might want to get your mid pipe and try what I did open trunk, seats down first. just a suggestion
