In a parking lot windows down it is glorious. The loud drone noise ~ 3000 rpm is not something I like, but again other people love it. |

I have the MPE, and coded ASD off. I prefer the ASD off. I do hear slight droning at highway speeds. I ordered the Akrapovic catted DP, so hopefully that adds a better in-cabin sound. If it doesn't help with the droning, then I'll go with the full Akra exhaust instead. I'm also going Dinan stage 4 in two weeks, so that might also affect engine sound slightly.

I am quite disappointed in the MPE - Fabspeed SporCat combo. The car is almost undriveable between 2800-3200rpm...at least for me anyway. I find myself having to be in gears higher than I usually would be (i.e. 4th instead of 3rd) just to keep the rpms below 2500 to avoid the horrible drone. I am waiting for the weather to break so that hopefully there will be a local meet where I can listen to what other guys have done -
different systems/combos/etc. There must be something out there that sounds better...maybe once I get past break in it will be better?? Hindsight tells me I should have stuck with stock exhaust and just purchased a different aftermarket system. |

Real oem shows the part number for the resonator.
http://www.realoem.com/bmw/enUS/part...;q=18307854718 It can be found for around $350 USD Question is who's going to be the first to try. Location of the resonator is likely important. |

Just spoke to a knowledgeable gentleman by the name of Aron from Vibrant Performance in Ontario. Was told that adding a resonator would likely be helpful as the drone at a certain engine speed is due to the vibration frequency of this long exhaust tube.
As for positioning he did say that if the drone is at lower frequency like we see 2800-3000 RPM, then the resonator is placed closer to the front (the cat). Which corresponds to where the stock resonator lives. Do we know the tubing diameter of the MPE? |

Of course, if I'm driving aggressively, I don't pay attention to that, but then the drone wouldn't be an issue and I wouldn't need to keep there for long. |

Why does choosing comfort make the drone so bad, at 3k rpm it's terrible? In sport or sport+ I don't think there's much drone at the 3k rpm point. Certainly doesn't bother me. Is it something to do with ASD? I drive in sport+ and it's fine, whether it would be with a sports cat I can't say.

All the resonator is doing is breaking up the wave so to speak. The resonator is basically a perforated tube with some fibreglass packing around it. That's my understanding anyway |

lol you do realize if you want it THAT loud inside you'll have actual drone.
clearly from the outside it sounds good so who cares what it sounds like on the inside? you're not driving a v8/10/12 soooooooo roll down the windows or listen to some good tunes. #firstworldproblems |
