Looking for some help. Ok, so I have a 15 gti with revo stage 1. I just put on a CTS catted downpipe. I also used their 90 degree 02 eliminator and I also installed a short straight one from amazon. I went one day then the CEL came on. 2 questions: #1 should I remove the short one and just use the 90 degree one and will the CEL go away? #2, if I go stage 2 and leave it as it is, will the CEL go away? Thanks for any help!!
I'm not familiar with the spacers that you're using, but the Vibrant J spacer with middle sized insert has kept me CEL free with CTS catted since Oct; ~6k miles.
