I have Fast Intentions test pipes on my '09 370z, I have never seen the CEL light come on.
Installation instructions followed to a T by Real Auto Dynamics in Queens. I dont have a pdf to the instructions but I'm sure FI does.
Its not the product, it was your installation.

i have had FI TPs on my car for about 38K miles and 4 years now. never has it once thrown a CEL.
only time I've seen them throw CEL's for others is with incorrect installation that had damaged the O2 sensors.
