Different high flow catted pipe, but the result is still the same.
They cost more and they have a high failure rate which will degrade in about a year or two. Return them while you can and save money by buying a set of catless downpipes. You can suppress the CEL by having an aftermarket tune on it. My Cobb Stage 2+ map suppresses this CEL even though I have a set of catless downpipes on my 135i or use the BMS downpipe fix.

+1 about still needing the BMS dpfix in order to show readiness.
