Well as the title states...I recently installed my invidia exhaust and after a few days the CEL came on which i knew would happen, but when I got it checked, the P0411 code came on. I searched and noticed this happens when you install a new intake but didnt find anything on the exhaust install...Any advice?

 

They are unrelated.

 

i agree. p0411 is usually related to incorrect vacuum lines. i got the 0411 when i had my check valve on backwards.

did you for some reason or another move things around in the bay when you did your invidia install?
