M Performance Exhaust
Hi guys,
does anybody have an M Performance exhaust? If so can you please tell me if when you start up the car, if only the drivers side exhaust seems to emit sound/smoke? I suspect the exhaust is set to only open one flap on startup, then open up both once the car is running? Is there any way to set to open up both flaps if this is the case? |

Press sport mode before start up and both valves open, it effectively creates a straight through as opposed to re circulating the exhaust gases, where's the pleasure in being an Eco warrior . The sports exhaust in combination with the selected mode instead of recirculating gases twice by- passes gospel according to BMW emergency services veteran

Press ignition button once (feet off pedals) car powers up change driving mode , press ignition button again start as normal (auto/manual)
You can actually hear flap valves doing something by switching between modes after 1st power up button press Last edited by worktolivelife; 12-13-2014 at 11:17 AM.. |
