From a performance standpoint...
 

Is the exhaust from Fast Intentions superior to NISMO or others out there?

I really don't like how low the FI sits, and I'm not a fan of the price tag either, but it seems to have one of the better dyno results.

if they fit right ^^

The FI sits low to facilitate airflow (as I understand it). Very few bends in the system.

Personally, I think the price is a bargain for what you get. You can't imagine the quality of this system until you've examined it up close.

I've installed many aftermarket exhausts in my car-owning life, and none were are well built or perfectly fitted as the FI.

Ultimately, it comes down to what you like in terms of sound and performance, and what you can afford.

my FI cbe is for sale if you are interested. great condition and priced right too, check the link in my sig. as far as performance goes, nismo is one very small step above stock, the FI cbe kicks ***, in the upper revs, and if you like the volume.
