So for the last two or three years I have passed smog with some homemade O2 simulators. They worked great but even with my trying to seal them up good, I must have gotten some moisture in there because one side shorted out.
So I went ahead and got these cat simulators because I always wanted to try them to see how well they worked. I had to get the 90* elbow extensions because of the limited space around where the sensors are located on the mid-pipe. But as you can see they are basically like using anti-foulers or spacers but with the added bonus of having a catalyst substrate in there. So we will see how well these work. I will probably be tossing them in next week sometime and giving them a trial run.
