After market exhaust choices
Folks I was looking to upgrade the exhaust for M2C, came across this video
I was thinking of doing AA midpipe, but liked the deep sound of AFE as well, not looking for a very expensive option either. Has anyone any experience with AFE exhaust. How much usually does it cost to do midpipes or changing the whole exhaust. Thanks for your input. |

i'm curious if the AA midpipe also works with the Dinan exhaust. I think it should but i would love to hear it paired up. I was thinking of getting the Dinan exhaust myself but pairing it with the midpipe for more low growl.

Thank you for sharing our video
Top 3 in my opinion, REMUS, Active Autowerke and Dinan

I still love my Remus/AA mid combo. Sure, it's loud but I think it's absolutely the best looking option alongside akra. Absolutely nothing hangs below the CF diffuser. I didn't have a commute pre-covid so I like driving to be an experience that hits all the senses. The cold start, burbles, and loud pops during shifts make me giggle every time. I'll take some pictures and try and take a good video after a wash today.

There's a video on Active Autowerkes instagram with in-car and audio footage of their new equal length (EL) exhaust on an F82 that sounds righteous! I reached out to them the other day through the "contact" link on their website to enquire if/when they may be producing this for the M2 Comp, but haven't heard back... If it were going to be sometime this summer or early fall, I'd be inclined to hold off on an exhaust purchase until then bc it really seems to sound much better than anything else I've heard, including the Milltek EL exhaust. If not, the Dinan option being full cat-back seems really nice at a great price! I feel like a lot of people on this forum are anti-Dinan for whatever reason. Having visited the APR/Dinan facility in Alabama, I feel like they are a really top notch engineering firm

Akra-Evo best quality, perfect fit and serious drop in weight. Deletes secondary cats...but it's not cheap. Plus there is a noticeable difference in power.

Yep, Looks like it's in the works! Here's the in-car video I referred to before. M3 though, not M4. Makes no difference... |

cannot go wrong with the AA Mid + Remus Race or Sport.
it can be quiet in Efficient Mode. in Sport+ Mode, it is mild/moderate during cruising. it only really gets loud when you really step on it or during initial cold starts but then settles.

Agreed, but got mine second hand so it didn't hurt. As bad

It still retains the secondary cats and requires cutting the stock exhaust system |

Do you have a clip of pure AA exhaust sound (CAT back) portion. Also is there any meaningful hp and tq gains with AA exhaust. Thanks |

First video in that list I sent you it had OEM cats on.
I never did a before and after dyno to confirm power gains if any. Active Autowerke can confirm if they have any figures they have.

The "oh shit" volume is maybe for 30 seconds and then it settles down fully at maybe 2 minutes. Then, I do drive out of my neighborhood in closed flaps, efficient (hunt for red October) mode.
