hey i have a 2004 sxt and i might b losing my catalytic converter. does anyone know of anyone who makes an downstream 02 sensor eliminator for my year i now howell makes them for 99-2000 but i can't find one for my car. or if anyone else from 2003+ doesnt have a cat and found a way to get around it

 

If you take out the 02 sensor you'll just get the CEL on all the time...if your going to delete the cat you might as well just make a spot for the 02 sensor so the computer wont scream at you. So no, i havent seen anthing like what you want for the 2nd gen Neons as of yet.

 

does anyone here have no cat with a 2003+ neon?

 

The down pipe on the OBX comes with the down stream hole in it for an o2 sensor. It should work fine. I only used a simulator on my 00 neon becouse about 4 months after putting the header and down pipe on my car. My light came on. And when I tested it. It showed that the o2 sensor was not responding right. In truth it might have been a bad o2 sensor, but I decided to go to a o2 simulator to take care of the problem. And I put a plug in my down pipe.
