secondary Cat.. i vs xi
I have the e92 n55 xi. I'm wondering if I remove my secondary cat if it will make a difference on my exhaust note... Does anyone have a picture of the two stock exhausts side by side? Where is my secondary cat located?

Correct me if I'm wrong..
Is this it? Because I know one is on the downpipe (which I swapped out for catless DP) So, we started with four... I removed two... If these are the remaining two, then I can remove these to make..... zero! The cats towards the top are only found on xi right?  #1 & #2
