If you didn't know already Status Gruppe offers headers and section 1 for our cars. All the options aren't listed under Z4m but if they have it for the e46 M3 they will build it for the Z4m at no extra cost. That means catted section 1s with bungs for those wanting to run the cat less headers and not throw a CEL. I just ordered a resonated section one to get rid of the rasp on my AFE exhaust.
