DP, Midpipe, or rear section?
New m2C owner and owner of many a BMW with modified exhaust. Things are less clear for me on the m2c. Here are my former cars and setups I ran:
e92 335i n54: catless downpipes, stock midpipe and rear- overly raspy e92 335i n54: high flow cat downpipe, stock midpipe, 335is rear section- great e92 m3: catless downpipe, resonator, high flow secondary cat, stock rear- great I just finished break in on the m2. Will probably just run a CS map. The stock m2 comp is just a bit too muted in sound, both intake and exhaust. The burbles in sport plus are fairly loud. I plan to remove the charcoal filters and probably add BMC filters. I would like the exhaust to be 15% or so louder and I'd like to disable the ASD. For the exhaust, I am debating the following independent of eachtother: AR Resonated Downpipe- Save 7 lbs, but lose warranty, don't really need downpipes for a mild tune like the CS AA Midpipe- Saves 10-15 lbs I think? Smoother sound? A bit of power? Rear Section- I would go for something fairly conservative here, maybe a (gasp) Dinan or MPE, or sport axel back, Save 10-15 lbs. In the past I would have gone downpipes immediately but the s55 is making nearly enough power stock and therefore options 2 and 3 are a bit more appealing to maybe keep warranty. Anyone else is going the OEM+ route please chime in. - |

Can't go wrong with Active Midpipe and/or REMUS exhaust

After hearing a MPE M4 w/ catless DP's and another with comp exhaust, stock DP and no secondary's or res, I'm convinced a pair of catless DP's on the stock mid section is perfect. You get the extra sound with being too raspy/annoying with all the performance you need. The rear end would be great stock or something mild, maybe a Dinan exhaust, etc.

Judging by how the driver's side piping comes together it might be a very close fit where the Remus would be pushed out very slightly or one of the pipes may need cutting: We are looking for someone local to fit this combination if any OC or LA forum members are interested in this set up |

This is what I've just had done yesterday. I also installed the ASD bypass and I'm eager to get out in the dry to really hear what this setup sounds like up close 😎
