Just another question. By installing the mid-pipes, you are removing the two cats. Is this legal from an emission standpoint and will it void the warranty?

just checked their site, showing $1139 and shipping is free. That is still quite less. Too bad I missed on the $999 shipped

There is some confusion i have regarding cutting. Looking at the first post pictures it sure looks a lot different in where one would cut compared to the on line manual. Would like to clarity prior cutting. Hopefully I don't have to line up and than cut. Hoping there is an actual measurement location so it can be very close to match up pipes. |

I am going to need to get back under the car and make a few adjustments, because the mid pipe rattles against a heat shield at certain throttle positions now. It's a bit too tucked up - need to get a bit more clearance under the car. Should just be a matter of monkeying with the band clamps. Quite happy with the sound though, especially with the valves open. The sound you get if you dump fuel and lift is nasty in the best of ways. |

I only have 1200km on car, so will wait till 2000km service before I'll install it. Question - did you cut the pipes with exhaust still on car or removed muffler as well? |

With the valves closed, only a little bit louder. But actually loud enough now to hear gear changes, so that's a needed improvement IMO.
With the valves opened, plenty loud enough. Deeper and with just a bit of rasp. I plan to throw on the VSC-2 valve controller and I'm happy with the exhaust. It will actually be nice to have a volume knob when I want one. Neighbors and passengers will appreciate this too. *Edit* I should also clarify that ASD is off in my car. I came to accept this car would never match the S65 in sound long before I pulled the trigger (and I had mine loud with a Challenge race midpipe and a Gintani rear). But this setup will be enough to do for me without dropping a stupid amount of cash. Last edited by evolved///M; 01-22-2019 at 11:06 AM.. |

Decided to use a carbide sawzall blade with the exhaust on the car. Really didn't want to drop the whole exhaust, a little tricky but worked well with out cutting the heat shields. Prior installing I wanted to give AA a call for correct cutting measurements. Andrew help me since the PDF manual on line was a little confusing seemed the MC2 has different measurements coming off the rear welds of the resonator over the m3/m4. Glad I called they send me a different manual via email than what was listed on the site. Drive side is 6 inch back from weld and driver-side is 1 1/2 back. All went well, only leak which i foreseen prior installing was the ball joint fitting connections. I understand why they are used though they were not perfectly round and would not seal perfectly regardless how tight you make those band clamps. Took them apart and added sealer. Other then that it was pretty much text book easy install.
The sound.... Its just about perfect considering what what removed (two secondary cats and resonator. Thought it would honestly be lowered. AA did a great job of adding this 1 large pipe connection which seems to help remove rasp and add a lower tone. Its not loud at wot, yet the burbles are fatter and wetter on decel lol. There is a tone/hum and different rpm's, not really a drone but surely a new noise related to the exhaust which is pretty cool too. Performance... surprisingly I could actually feel a small difference. She pulls great down low but kind of falls a little on its face upstairs but to be expected with the detuning via BMW. All in all I'm very happy with the sound for this modification, doing an exhaust on can always have positives and negatives so for no negatives. If I want her quiet, its so easy to achieve just by closing the flaps in normal mode, BMW really made it super quiet in normal mode lol. For those that think the M2C exhaust is horrible they honestly just don't have a clue since I'm very happy with the stock cat back system with this mid pipe upgrade. Thanks AA for the great product!
