Hello, I'm new here, nice to meet you all
I've owned a 205 c63s sedan and would like to install downpipe with 200cell sport cat
may I know is it necessary to remap ecu in order to avoid trigger engine light warning?

And one more question, any comments for MCT sport cat downpipe?

 

no it wont

 

So maybe, some people get them others don't, you could be safe and get O2 spacers to increase your chances of not getting them.

 

From what I have seen, the answer is actually “it depends” when it comes to high flow catted DPs.

 

thanks you guys, it seems that i need to try, haha
