No one will ever be able to convience me that a 370z is a loud car (Unless you have open test pipes or headers). With any cat-back I have heard they are pretty much a good tone with a moderate WOT sound level. From reading this thread though it seems like the HKS is the same as a Borla system on a high performance V8 engine. Quiet when it needs to be, but opens up when you need it to! I'd go with HKS imhxo (in my honest experienced and opinion)
