Bm3 And OPF m4 2019

[linquist]

Can someone clarify for me whether turning OPF off in the bm3 tune i can change the whole exhaust system an remove the filters completely or is it advised to get the remus OPF exhaust ( There the only brand i have come across that do one)

I'd message ProTuningFreaks directly on their website tbh. You'll get a definitive, accurate answer.

BM3 will allow you to code out the OPF sensors from the ECU. Then you can do whatever you choose with the exhaust including removing the OPF’s.

I’d remove them and see how you like the sound before placing 2.5k on an exhaust system.
