MPE exhaust -

MTHX · 10-17-2015, 03:18 PM

Just a little question.

I Just get my new 335xi with MPPK kit.
It is normal that just one side of exhaust is working when cold start?
I didn't check after a ride if the two side work synchro togheter.

Yes, thats normal. At high performance and when the system is hot the left side also opens.

When you cold start the car, it only uses one of the two exhausts, I'm not sure to why this is but I remember reading it has something to do with warming the car up quicker. If you want to have both flaps open, simply put the car in Sport mode and tap on the gas, you'll be able to hear the flap open up the other exhaust. Congratulations on the car!
