i'm still debating on if i should run mufflers or not...i like loud really like louder and love loudest...but hey..i'm 17 with good err semi good hearing....i just don't like some of the sounds the mufflers give off...some of them sound way to tinny (lil bit of a rice sound) and others sound hollow...my aunt has purple hornies glasspacks on her dakota and they sound good...has anyone else used those??
