It's not the cat that gives it that hiss. It's kinda just how the motor sounds. It's almost unavoidable with HFCs or test pipes. Resonated pipes help, but it'll still be there.

Also I don't know if it sound stupid or not... When I sit in the car and stand outside the car(let other people rev it for me) the exhaust note are very different!

When I am in the car, I don't really hear the hiss sound so I don't bother.

Yeah, it's really only on the outside. The only time I've seen the hiss go away is when you stuff a pair of turbos in the exhaust.
