Hello I'm new here and just bought a brand 2016 ST just 10 days ago. Now I'm looking at getting a exhaust system for it but having trouble really deciding because even with YouTube videos of the sounds of them we all know that in person it sounds totally different than a recording. So what I would really love is if I could get a ranking list of cat back exhausts from quietest to loudest and if at all possible decibel counts of each. I'm not after a stupid f***ing loud exhaust note. I would say my ideal exhaust note would something simalar to how the newer Infiniti car's exhaust sound. Deep and noticeable but at the sametime not like you can hear the car coming 3 miles away.
