Will test pipes trigger check engine light?

[DeHaldaswerth]

I have a set of ARC Titanium Test pipes that weigh about as much as a paper clip, and I bought them with the intent of further reducing the weight on my NSX. Can anyone tell me whether their use will trigger any kind of emissions warnings? (For those who have not seen the ARC pipes, they DO have threaded bosses for installation of the factory o2 sensors.)

It did not trigger any lights on my 91.
