Cats Question

Oreocookies · 04-10-2019, 07:16 AM

Hey Guys,

I am new to the forum and BMW ownership.

I recently picked up a manual 335i in mineral white and have over the last few weeks been slowly amassing a list of mods cosmetic and performance related that i would like to do.

I am hoping someone can clear this up, i was looking at getting a remap and looked into a catless downpipe.

Now am i right in thinking that the E92 N55 (2011) does not have any cats in the midpipe/ centre section and only has them in the downpipe?

Thanks in advance

I'm no expert, but RealOEM seems to show a CAT on the downpipe only, so no mid CATS
