I installed my catted usp downpipe with the 90 degree angle O2 spacers about a week or two ago now and I just got the check engine light. I plugged in my wifi obd scanner and scanned it with the dash command app and it said O2 sensor slow response rich to lean bank 1 sensor 2. What exactly does this mean and also I've noticed my gas mileage has been a little less then what it usually is. Thanks for any insight

Yes, I talked to Arin @Apr and he said to remove the precat spacer. So I removed it probably at the end of January and I have not had one code since. After I removed it my gas mileage started returning back to normal in the 26-30 range and not 20 mpg like I was getting when I had the precat spacer in. The precat O2 sensor is purely air/fuel ratio and has nothing to do with emissions so there was no need to space it

Going to bump this as I'm throwing the same code but only after adding a rear o2 spacer..

the sensors are too far out of the stream guys.
shorter spacer or larger jet on modular spacers
