I searched and nothing came back on this brand. Z1 Motorsports has resonated testpipes for the Z/G for $179.00, has anyone used/seen these before?

That seemed a little cheap since the other brands of resonated testpipes are in the 300+ range.

Take a look:
Z1 Motorsports TPs

 

These guys are super and their products are top notch. The specialize in 300zx's and 350z's. I'm not sure why they are not more active on this forum as they are in others. Anyway, they have one of my 300zx tt's right now (turbo and chrome engine upgrades, suspension upgrades, test pipes, yada yada yada. I have used their clutches and drive shafts on my 300zx's and have had no problems with install or mechanical issues. They are have a Z national meet on the 21st-23 of this month I believe (I guess I will wait to pick up my 94tt then). Once I have gotten it back, I will send my 350z down for its FI mods. Most of the turbos they sell for the 300zx, for example, are a lot cheaper than stock, or upgraded HKS, JWT, etc., but the use the same parts as Garrett ala HKS, JWT et. al. So, IMHO you can't go wrong with any part that is produced by Z1. And, if you think about it, how hard is it to make a decent test pipe (with the proper equipment)?

 

I agree, I was more worried about the resonator itself than the quality. They seem to be pretty well liked, I may give it a shot.

 

im torn between this UTR and Fast In

 

I'm the same way, but I think I may give them a shot, do some before and after videos...I'll let you know.
