I have stromungs and it's ever so slightly louder then stock. Any less volume and it wouldn't be noticeable IMO. I added catless headers and now it's properly "modded sports car" loud but not obnoxiously racecar loud. Sounds great and no rasp but it does drone however especially when I have the top closed in my roadster. Top down no problem. Trying to go louder honestly but afraid of more drone
