I have resonated test pipes with the “cel fix”. When I run them with no extensions I get a catalyst deficiency code. Now with 45 degree extensions I get a too lean code. I have these short extensions but the o2 sensor has clearance issues. I looked it up on ChatGPT and it recommends welding in a new o2 sensor part and use a j-style extension. I have inspection soon and am willing to the cats back on just for inspection but I wanna put the test pipes back and hopefully with no check engine hoping to get lucky next inspection.
