GLC43 AMG
Talking O2 Spacer Sensor / CEL fix (adjustable?)

hello my fellow Mercedes friends;

i just received catless downpipes for my 2021 GLC43 & will be installing them next week. in anticipation of the CEL nightmare -- can anyone link me with a spacer, preferably adjustable -- that you have had good experiences with regarding eliminating the CEL?! so far, i have been told to look for one with a 90 degree angle. i see CTS has one like this, not sure though: https://www.ctsturbo.com/product/cts-cel-eliminator/

i saw some people talking about the mini-cat extenders, but worry how that will affect the overall fuel distribution / performance.

all and any advice is immensely appreciated.
