Good afternoon,

I am planning on installing catless headers on my 2011 328xi. I have heard that the HZ racing headers are almost identical to the AA headers.

After that, I want to attempt to install a 335 exhaust that my buddy has laying around.
I know you need to relocate the charcoal filter, and replace the trunk storage bin, as well as the heat shield from the 335. I have all of those already.

I am wondering if the aftermarket headers will fit the 335 exhaust, I have seen other people do this and I think it should be no problem.

I am also wondering if I need to weld new hangers on the 335 exhaust, or they are in the same locations.

Any help would be appreciated. Thanks.
