F30 Exhaust Flap Disabled?
Chipped or not, find my N54 smoother w/more torque off the line with driver side exhaust flap line crimped. Really, big improvement.
So, gotta wonder: Does N20 respond the same? Found a few like this but didn't see whether feel is improved like N54. Gut says it should....
You F30 owners - who's got info?
