BM3 Stage 2 93 Oct - Need downpipes?
Do I need new primaries for a Stage 2?
Do I need new secondaries for a Stage 2? I'm fine with secondaries but don't really want to do my primaries (CEL and smell). Debating doing all of these just wondering if I can get the tune now and install my secondaries later or need to do them first? |

you need primary catless or high flow catted for stage 2.
secondary pipes are not mandatory

Full catless primaries/secondaries here. Has a smell if in an enclosed space or at a red light with windows down, but otherwise not an issue. I’m happy with them. But everyone has their tolerances 😅

how much louder did it get? I'm not too interested in it being SUPER loud.

Can you code out seeing the CEL with bimmercode or is it always on? I'm not sure if that'll bother me or not.

you need a flash tune to suppress the code.
