Out of all the HFC’s you listed I would opted for the AAM HFC’s. No matter what aftermarket exhaust you install it will be louder the only exhaust that will probably be only a little louder than the stock exhaust would be the Nismo exhaust. If you are looking to drastically tone down your 370Z you will have to install aftermarket HFC’s or the stock Nissan catalytic converters. Test pipes resonated or not will be quite louder. In your country what db sound from your exhaust is considered to be legal?
