Very nice!
Solid content !
As a certified BMW Tech I can confirm that would of been a $1600 fix, but after figuring out the actually problem... I would of doubled it.
Hey man question, are you still running your JB4 tune? How has it been after the 2 years? Other than that has the Catless or intake brought you any problems? What is your current IG to DM you with some questions I have?
I clear the CEL from the catless downpipe either with my JB4 or my OBD reader. Other than that, my car runs solid as far as I can tell. Be sure to keep up with regular maintenance (maybe even do it more often if you got a tune).
Me: if you dig a 6ft hole, how deep is that hole?
BMW: about 20 ft
