Dinan Stage 1 with MPE or Dinan Free Flow?
Hi all,
I have my 2018 M240i on order and debating what to do about the exhaust. I have the MPE down on the order but am thinking about cancelling it and going with stock for now then upgrading later, likely to the Dinan Free Flow. My question is that I am going to go with the Dinan Stage 1 shortly after break in but am wondering, will I see a difference with it and stock exhaust vs MPE vs Dinan Free Flow? Ideally, I would go with Stage 1 on stock then upgrade to Dinan Free Flow later as long as running the Stage 1 on stock exhaust won't cause any issues vs MPE or Dinan Free Flow out of the gate. On another note, is the Dinan Free Flow any louder than the MPE? I am a professional and want some additional burbles and fun sound, however, when I am pulling away from a client's home, I don't want to sound like a street racer. Thanks |

If you want the best of both worlds (quiet when you need it to be and sonorous when you want it to be), my recommendation is to go with the Dinan mid-pipe only, instead of a replacement muffler.

Just curious, if you are just looking for a sound modification, then just the MidPipe, but if you are looking for a power increase (although not that much,. 5-6HP), then, free flow exhaust, correct? How loud is all of it going to be compared to stock?

I have the dinan mid pipe and 200 cel sport cat. Insane difference over stock. It's loud, I couldn't imagine getting a MPE as well. Cold start up is very loud, but mitigated by applying the throttle gently. Driving normal in comfort you can be quiet but switch to sport and the burbles are like gun shots. In comfort you can also hear the turbo whistle, which sounds pretty cool.

I want a lower grumble at idle but don't want it to be obnoxious. Had supersprints on my Z4M and it was perfect cut for me. My biggest concern, as mentioned, is weather one exhaust setup vs another is more or less ideal to use with the Dinan Stage 1. |

In Sport it is noticeably louder at higher revs and lots more and louder overrun. No drone. For, me, it is the perfect compromise. The car should have sounded like this from the factory.

Status, income, position, has nothing to do with exhaust sound. If you want it loud and to pop and burble, ask. If you want it quiet and to not do those things, ask. Status has nothing to do with sound. Maybe I'm being presumptuous. |
