Has anyone made their M exhaust flaps stay open?
Has anyone done anything like the m3 mod to keep the flaps open in the m performance exhaust the whole time? is this possible?
Any downsides to this? (apart from it being louder the whole time) Its kind of annoying double tapping that button every single time i start the engine. Last edited by badluck; 06-06-2016 at 05:40 PM.. |

You can look at the valve(s) super easy without putting the car on a lift. Just get underneath and look up behind the exhaust. I used the JRC kit and could install with the car on the ground. Other than valves, there is no reason for a wore to be going into the exhaust at this point.
JRC makes a dual valve version (for every other M). |

The BMS Can Flap Module should work, has more features than just keeping flaps open too

Turn on the car, foot off the brake so engine doesn't start, open flaps with bluetooth remote, then unplug the wire from the solenoid flap control on each side of the exhaust. In theory it should work, flaps will be stuck in open position. Let me know if it works.

Aaron do a version of their digital info display with a open/close valve option on it. control it via the screen or a button on the steering wheel. Works fro standard exhaust and the M performance one. Think its 200euro more for the exhaust option

By the way, isn't the valve always fully open if switching to sport or sport+? I thought I read something like that here... |

... or any point in purchasing ANY exhaust with a muffler ? If I understand correctly having the flaps open all the time is completely bypassing the muffler, right ? So a straight through exhaust would have the same effect while being much cheaper as no muffler or fancy controllers, as well as considerably lighter. Maybe Fabspeed Motorsport could comment on this as I'd really like confirmation and no-one has answered my previous comments on this. The reason it's important to me is I'm thinking of getting a Fabspeed muffler bypass system when I get my car.

With the Fabspeed setup you are bypassing the muffler entirely so it should sound more than just having the flaps constantly open. My Fabspeed Muffler Bypass should be arriving next week.. will know more after installing.
