Where could I buy the 3" N1 style topspeed pro1 exhaust for my Z? Seems like they are unavailable on their website.

The EBay one is very diff from the one at Concept Z and definitely not N1 based.... the latter looks like an HKS ripoff/copy... Probably part of the reason HKS USA is dead. Psh.

BTW, if you do your research, you'll see there's a reason it's not sold by too many places....
