i4 exhaust success from generic Alibaba

Finished the install and took it for a short spin, happy to report no CEL. The Mach 5 valve controller also seems to be working well and throwing no codes. It relocates the factory controller and uses it as a simulation for what the mach5 exhaust controller should do

As for the sound of the mach5 stainless steel exhaust. It’s a little too loud for my taste. It sounds like the piped in amg sound (I have the amg sound disabled) but it’s actually the exhaust sound now.
How were you able to disable the fake engine sound? Thanks.
