This exhaust is my No1 option at the moment after having the race system with secondary cat bypass on my M4 CP.
Loved it on the M4 and was a great system for the money.
I'd like to delete the OPFs and have the system from the primary cats back so just need to see who can code out the OPF sensors for me prior to installing.
My hope was on the BM3 but my car is a 2020 and has just been built and awaiting shipping to dealers so I surmise it'll have the new software locking the DME.
Really Interested to hear how you.like the system.
