While the OEM nismo exhaust is a quiet exhaust, it's definitely different then the oem 370z exhaust. It's much deeper. You guys are right if you sit inside your car you can barely tell the difference between the nismo and oem exhaust. But I've heard so many times when people drove away my car. It's noticeable deeper and I was surprised it sounds pretty mean at low rpm. Matter of fact many random guys on the street complimented on my oem nismo exhaust. But it's not very impressive at WOT which is why I got my HKS and very happy with it.
