1. High Flow Cat
Iím looking to fit a HFC without a tune. Would it give CEL? It seems some say CEL wonít be an issue whereas others mention a tune is a must to get rid of CEL.

2. Oil Catch Can
Iíve done a fair amount of research for a bolt-on catch can for F2x N55 in vain. I asked BMS if their catch can for E82 N55 would fit on our model. They say it wonít and added the oil lines are different for both models. Looking at the engine bays of them, I think the mounting position would be different as well.
Is there any bolt-on oil catch can for M135i that can fit without having to worry about modification/fabrication?

Afaik there is no word for any OCC's out. I don't recall anyone needing one either. (which is odd, as a fair part of M135i are being tuned...)

And for the cat, as long as you don't go de-cat you should be fine concerning CEL.
