Supercircuit exhaust header compatibility MCC vs. FCC CAT

Hello all,

Looking at the supercircuit exhaust header:

I am reading conflicting things on compatibility.

Will these headers be compatible with the 2023 mirage with MCC?
The only install examples I see are from pre-2017 so I think this is still a question.






From this post, it seems not compatible with 2017+ without some modification:

I don't know if that header will work properly on North American Market mirages. A lot of overseas models don't have a maf, basically have a different way of running in a way.
And compare where the front o2 sensor is located in the header compared to either manifold style Mirage. It might run like caca. I'd do some more readings.

Looks like car is still too new, all the exhaust components are for 2017 and earlier.
