The VQ hiss is normal and is amplified withe the gen 3 and FI. This occurs on deceleration wheather under load or not. A rattle is something you will have

 Hiss is status quo when you remove factory cats. Kind of like the flywheel chatters a lot. Normal for the platform. |

You may wanna check if all the gaskets are on right and there aren't any leaks. Other than that you're good. Test pipes tend to make the car hiss. FI exhaust has a hiss to it. Add test pipes and you got yourself a hissing machine that sounds glorious
