I asking this question because cant think of any other than Greddy what are the other systems that are available, also catback is better because it brings more HP right? and which one is not too loud? thanks

TOM'S Barrel is cat-back. I think someone else here got a cat-back system by Kimura, IIRC. Might wanna do a search for that one...

HKS does too. And I think Apexi.

Greddy is one of the best on the market. Quality and great sound. I have the EVO on my GS and it has a nice low note and throaty sound. Don't let all these system fool you when they say catback because it is actually from the middle muffler that the aftermarket exhaust hooks into which is a single pipe and the the aftermarket pipe Y's into the dual tails.
I also have Greddy on my 90 300ZX and that really sounds great and looks awesome with the 5" tips!
