I have searched for a week or so and most of the options seem to be for the DE.

What I have come up with is:
Megan Racing
TopSpeed <<< Just found this one out from CZP
Motordyne ART Pipes <<< Found a set of these in the FS Section


Is that all there is?

I am looking to replace mine but I hate the sound of a raspy engine so i have been looking for a resonated test pipe.

Check out the cnt resonated test pipes they fit the hr and 370z

 

I have Fast Intentions test pipes. I'm not sure if they still make them.

 

I'd look at Fast Intentions.They make all their stuff to order.Give them a call.
From what I've seen,all test pipes,resonated or not will have some type of
rasp.However,"rasp" to one person is not rasp to another lol.
I recently posted what I did with my car(S-Tune+HFC'S)to eliminate the rasp
I was experiencing at around WOT.I added some small tail pipe resonators.
They are about 5"long,install nicely in the 3" tips I have.They come in various sizes.
My rasp was elimated.The resonators also reduced some of the bass tones that
were a problem at steady hwy speeds.
