After you put them on you will say, " WOW I wish they were louder! " well maybe not, but they are not real loud. At about 1800 to 2100 rpm they are the loudest and you will find yourself cruising at those rpms to here the sound. And when you get on it you will love it. I had the X pipe and that was annoying with the top down, it sounded great part of the time but at times was too much. I cut out the cats on my stock pipe and they sound great, not to lound, just right. There are other set ups of course but the flows are a good way to go!!
