I have heard the resonated AAM short tail exhaust with the Berk HFC’s in person in my opinion it sounds great but, for some it could be too loud/obnoxious though everyone is different. The best thing you could do is try to listen to exhaust clips online and try to see if anyone has this exhaust combo on their 370Z that you could hear in person.
