Whose Stage II, then?

[BTD37]

The CEL comes and goes. Since installing the downpipe, it has popped up maybe 3 times and gone away on its own after a couple of days each time. There's a persistent pending code that shows up on obdeleven. Let me know if you want to know what codes they are. I'll try to remember to do a scan later.

Thanks for the update. I'm not too concerned on what the codes are. I was mainly curious to see if it throws a CEL. Was getting hopeful about this one as its way cheaper than AWE's CEL free DP.
