im sure they will get louder after break-in .. but right right out of the box, they are quiet . atleast to me they are, my other cars were flat out LOUD ! .. '65 coronet with worked 440, 3.5" pipes that dumped just in front of rear axle was LOUD ... previous exhaust on dart with glasspacks that exited right under quarter windows was LOUD !! I think i might enjoy some qiuet time for a while !!!
