Nismo Track Exhaust?

[Thefunk]

I'm looking to get the Nismo Track Exhaust for my Z. I've seen the comparison videos and after listening to them all, the nismo sounded the best in my opinion. Does anyone here have it and what are your thoughts? Also what kind of back pressure is introduced or eliminated/reduced over stock?

Exhaust update I wanted to share:
I plan on buying tomei type d dual exhaust
I emailed hks to see if they are making a ti and the said no and now plans to make one.
Just wanted to share this.

For nismo, all the videos i watched it sounds great. I am going for the tomei Ti for weight reduction. Keeping dual though, single on a Z is absurd.
