I think it would be louder and heavier. I tried to make my 590 cube 1471 blown hemi challenger quiet when I drove on the street. I bought the biggest mufflers I could find to make it happen. I bought a pair of stacks for a semi 4 foot long, 5 inch pipe, chopped a side flat and tucked them under my car. Certainly they should make it quiet? It sounded good and flowed good I'm sure but it was not quiet. I live hear in Detroit and have had people say they heard it from 2 miles away when I jumped on it, the idle set off car alarms all over. I think you would have double the sound. jmo
