Installed my long awaited EST downpipe and touring exhaust a couple weeks ago with fresh front and rear O2 sensors, and have gotten a CEL for the CAT after a couple days. Cleared it, and it came back again couple days later.
Looking around, I see that a spacer is recommended for the rear sensor in aftermarket downpipes, but many of the threads are pretty old and I'm not sure if EST has updated their design or not to mitigate this. The rear position essentially IS a spacer from what I can tell. Here's a photo when I was rough fitting together.
And one with the sensor in as i was getting it all installed.
I've also read that having too long of a spacer can cause a CEL light too, so there's a nice middle ground somewhere?
Does anyone have experience or recommendation for this configuration? If it's needed, likely have to be a 45 degree one to fit.
Thanks!
