Hallo guys , i would like to kindly ask you for advice. I have a headache from purchasing catted downpipe, can you pls someone advice me which one should i buy ? (availible to purchase from Europe) I would like to go for Stage 2, which is sweet spot for me. I read lot of threads but still i cant make a decision.

Considerations:
- I have OPF version of engine ( Europe version)
- dont want to feel the smell outside car
- i will be happy if there will be no error codes because of OPF off or CAT
- i dont want car to be louder ( or not too much)

Questions
Is it enough to flash MHD to let the ECU know that OPF si off ? or it needs to be uncoded?
Do i need to change air intake ? (i would like to keep closed version)
Is 300 cell enough or should i go for 400 cell?

Is there anything better than this ? https://www.psr-parts.com/collection...46984802140486

Not sure if mike from x-ph ships to Europe.

You don’t need an intake. If you flash mhd it should be good enough

Yes he send, but there is no info about OPF filter, if it will fit correctly.
