Bought a 2011 e90 as a project with 80k miles on in. The car had a valvetronic cat back. I replaced the mid pipe with Macht Schnell pipe with PLM HFC. CEL i can deal with but the smell is horrible. My F90 only has two HFC cats left and there is no smell at all. Any recommendations for other HFC?
TIA

means those PLM HFCs are doing a terrible job of scrubbing the exhaust gasses. I would replace them with something like a GESI. Or I know people who have used the OEM secondaries and weld them in place.
