MPE owners - how do you like it?
Considering the MPE for my 2015 M235i.
1. Any drone in the cabin? 2. Any increase in cabin engine sound? 3. Will the exhaust affect performance or reliability? Been doing some research, figured it'd help to hear firsthand. |

no power gains, not loud enough, high cost. Get something else.

Here are my impressions:
1. Any drone in the cabin? No 2. Any increase in cabin engine sound? Yes 3. Will the exhaust affect performance or reliability? No It is slightly louder than the stock exhaust, just the right amount for me. Roll the windows down, put the car in Sport+, press the DSC Off button for 4 sec, and put the gear selector in S mode and you will get a cornucopia of unexpected and delightful aural entertainment. As an added bonus in this mode you get a gas pedal with a proper linear throttle response, just like a real race car. (note: some people reported that this procedure put the car's suspension in comfort mode, this doesn't occur in my car) (double note: Yes overly cautious people, you are driving with most of the nannies off, so you have to behave like a responsible adult. If that's not possible keep your car in comfort mode ) |

MPE + DP in my opinion sounds amazing, just MPE is only light increase in sound, almost no increase in cabin, but definitely noticeable out side the car.
Or you can just stick with stock cat and go with a muffler delete |

putting car into DSC off puts it into comfort mode throttle settings, u'd get better sounds leaving it in sport + or sport mode.

The DCS off mode with S mode transmission also puts my car into a more aggressive shift mapping than sports+ with S mode. Based on reports, some cars seem to operate differently. So give it a try, if you don't like it go back to your favorite flavor. |

2) Yes, there's an increase in interior sound. You hear more exhaust. Still very refined inside. 3) No affect on either. BMW makes no claims on HP gains. Dinan and many other aftermarket companies claim ~5hp/5tq gains with similar high flow muffler setups. I felt no change, but the change in sound is worth the price plus the OEM fitment is great. The sound is intoxicating. A cross between muscle and exotic. The exhaust overrun (i.e., burbles are far more prevalent as well). I suggest ordering from Brian Keller at BMW Sun Motors. He gives the best new prices. |

Per BMW, you get around 80% of the overrun sound in DSC Off compared to Sport. I can't tell any audible difference. Both settings have a lot of overrun, at least in a 6MT.

He's always the cheapest and manages to have everything in stock. He typically ships same day. I just ordered the MP rear diffuser from him 5 minutes ago. |

I think it's perfect for what it's designed for. Which is a nice tone and no rasp. Here's my MPE w/ 4" catless DP
Still has resonator between the cat section and muffler, to me it's the perfect tone, volume and over run. I could imagine it being slightly better with a high end axle back, but I'm content. It also has an oem+ finish which helps keep things looking factory. Exhausts are one of those things that each person has preferences for. Best bet it try to hear one in person, as the videos can distort a lot of pure sound. My video was done with a mic, so it's as about as clear as I could get to show how it would sound in person. D |

You didn't ask the best question, does it sound better? YES!

I've debated endlessly over this before I ended up purchasing my MPE. I searched countless threads and watched all the videos.
In the end, I would say it exceeded my expectations. There are some that say there wasn't much change in noise but I can tell you for a fact that there is a night and day difference in sound. It's much more aggressive and burbles often under the right circumstances (Letting off the gas below 4K RPMS or down shifting with revs hitting below 4K). There are some that say the MPE is too quiet and I have to say that it's a matter of preference. I think it is plenty loud while maintaining stock levels of noise in comfort mode (which was important to me), I do not want to explain to anyone why the car is droning on the highway. I made 3 videos that I just uploaded to Youtube for reference purposes. Hopefully this will help you and anyone else that is on the fence about it like I was. Stock note for reference Right after changing exhaust (not broken in yet, oh yeah did I mention the exhaust needs about 500 miles to 1000 miles of break in before it gets even louder?) After break in (But inside of a garage so it is a bit louder) Let me know if you have any questions. Last edited by Bmw.Fan; 04-19-2017 at 11:00 PM.. |

I really just want my car to sound like the RS3 I drove in Stockholm. That thing is perfect from that perspective. |

Also, if you need to buy, Check with Brian at Sunmotorcars, it's where I got mine for $700 without tips (You can reuse your stock tips, which I preferred anyway). -Tony |
