If the hiss occurs during acceleration then it's not normal and might be an exhaust leak. If the hiss is only occurring during decel then that is just a feature of the VQ motor although I can't recall anyone not running TP's or LTH's complaining about it.

That doesn't sound quite right. Get under the car, make sure everything is in place and bolted up properly.
