Does the MPPSK have a different exhaust note on Sport vs. Sport +?

NYG · 04-26-2017, 03:18 PM

I noticed today when I was showing it to a buddy and it sounded different between both but it could have been just me...

raqautle · 04-26-2017, 04:02 PM

i dont have MPPSK but mine sounds different only because i have sport set to chassis only, not drivetrain. Putting it in sport+ affects the drivetrain and therefore exhaust

CruzM3 · 04-26-2017, 04:06 PM

No it doesn't. It's the same.

mannymazz · 04-26-2017, 08:45 PM

Exactly the same the valves are either open or closed. You were probably driving harder and temperature effects the sound a lot I noticed.

The shift characteristics on the auto are changed slightly and the changes in sport+ can be harder when NOT pressing on than they are in sport which will change the sound of the change itself, but speed for speed, they're identical.

The only difference I see in Sport+ are shift changes and traction control changes... thats all

At one point right after I installed my JB+ I was getting over run (pops) in Sport + only. Comfort and Sport sounded identical. Its back no normal now though. Still dont know why

The sound is the same Sport or Sport+.

EBIIMKKP · 04-27-2017, 10:48 PM

No difference

2018 440i mppsk. Sounds the same in sport and sport plus..... which is great!

flog350 · 05-05-2017, 06:39 PM

Anyone find the drone (MPPSK on Sport) at highway speeds to be a bit too much or is it just me? Also, there's a slight vibration/buzzing sound around the center console on acceleration. Driving me nuts as I cannot find the location. Any help to reduce drone and vibration buzzing sound will be greatly appreciated.

*Yes, I know I can change setting to comfort mode during highway cruising but I can't stand the throttle response in that mode.

riskmaker76 · 05-06-2017, 07:34 AM

I find it tame for high flow exhaust...Your not use to high flow exhaust...

Isn't much you can do outside changing the exhaust back out out to stock or pressing the comfort button when settled.

mine was rattling against heat shield at idle i was going to look into it and then it just went away on its own after a couple weeks, must have settled in different position

i think the rattling he is talking about is different, from the interior, light loose plastic sound ...at least that is what i have
