5 code after O/R H pipe ?

I eraser the code the other day, and yesterday it came back, so today I pull the code and it say I only have 1 code about

* P0420 Catalyst System Efficiency below Limit - Bank No 1.

so I guess im good, my state dont care about emission, so I guess I dont need mil eleminate. Thanks guy.

That code is due to the lack of cats. The O2 sims (MIL eliminators) will take care of the code. The computer is trying to compensate for the lack of cats so it would be a good idea to get them anyway.
 
The cops will know because you cannot get the sticker that says '08' or 09 (the year) unless you pass inspection. The sticker is also a dffrent color than the last years, so it'll stick out like a sore thumb from all the other cars around
