How were you able to disable the fake engine sound? Thanks.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.
