That really sounds great MASHCT! Questions:
1. In the first video there are no burbles, is that ECO mode or is the valve controller closed? 2. Second video you say M2 activated...I assume it's in Sport or is that Sport+? 3. What diffuser is that? It covers the can nicely. 4. OK this one is stupid, so please everyone judge me (this is Bimmerpost after all, my feelings would be hurt if you didn't )....my avatar is a piece of poo so you all already know I have poor self-esteem and overcompensate with crappy humor (bah-da-boom)...but here goes: How much louder is it inside valves open vs closed? I drive in Sport exclusively for the linear throttle response, don't care about the burbles, but I like a sportier note. One thing about this car is the H&K is WAY better than the F80 H&K ever was (with B&W coding that is) and I really appreciate my music. I want to be able to hear it....had the titanium BMW MP exhaust on my F80 and that thing was a bit drone-y and would drown out the music on days I wanted music...I suspect a "Jekyll and Hyde" exhaust might be better for me - quiet valves closed, but if I'm in a "speedy" kind of mood and taking my stress out on the accelerator pedal (we all have those days right?) I want to hear the car with valves open and noticeable exhaust note, for me...I don't care what others hear outside the car...how does this setup do that way? I suspect for me I'd need this setup with a valve controller and perhaps just code off ASD inside the car to quiet the cabin a bit and trade for actual exhaust sound. The stock exhaust is SO quiet inside that I need the ASD on now just to know where I am rev-wise. Maybe I just need an axle back to start (or wonder if a midpipe would be better to start - open to suggestions), and add from there if needed. I just suspect that the midpipe makes it louder in the car than out. Anyhow, this is just me musing, but man that sounds great. LOVE that you have no drone, that is so key. Loved the prior MPE, but the drone at certain RPMs could be a mood killer certain days.

See my answers after each question. By the way, how many Katie Courics do you weigh?

I very rarely hear of drone with the G8x cars, no matter what midpipe/axle-back is used. Seems the droning starts when DPs get installed.

The only time I experienced drone was with the active autowerke Gen 1 equal length + catted downpipes + active autowerke axle back. this is now fixed by getting the Gen 2 equal length instead with the extra resonator

Thanks for being the guinea pig! I have the Dinan mid pipe on my G80 and it's awesome, but just missing *something*... was thinking about swapping to a single mid or adding the MAD rear section and this might be the move now. Thanks for posting! Sounds great!

Be confident in your purchase if you go with MAD. No one paid me dime or discount to say any of this, either.

Wife ordered the Dinan mid-pipe & MAD exhaust with carbon tips for me. Would have preferred black but didn't like the color of the logo on them. At least the red logo on the carbon tips will match the red car.
I got the wife new intakes and a custom leather & carbon fiber steering wheel for her X3MC. If she didn't enjoy her cars as much as I do mine, I'd be in trouble, a lot |

Really enjoying the mad exhaust paired with my AA equal length midpipe. Would highly recommend mad’s products (have their intakes too).

Did you do the front mount? If yes, can you hear the induction sounds? I really like MAD'S products. Excellent quality and designs.

Screen shot of a sound meter readout. SST controller set to 100% open and M2 mode activated. Idle was about 80db to max 115db with a decent rev. I am sure it will go louder if I really got on it.
The minimum 20db was ambient sound before I started the car. Normal outdoor sounds with breeze & birds. Of course I had to ruin the bucolic setting with car sounds. My neighbors were thrilled. LOL

Howdy Mike! No... I wasn't thinking and missed the opportunity to measure it. And I was kicking myself at the installer's for not asking to do it before they took it all apart.
If I see another M2 at any of the car events I go to that has a stock exhaust, I'll ask if we can do a test. Maybe someone will see this post and do a test with the same app on a galaxy S22 ultra. It's Sound Meter by Splend.

Yup it is the quality of the sound that matters to me. I don't really like a super loud exhaust. This is a great combo of volume & deep roar. I am so curious to know comparison to OEM!!

I was probably about 3' away from the exhaust & directly in the middle of the pipes. Any closer I thought would be too close to the bumper & not really picking up the full sound coming freely from the pipes. Should I check again with the phone in a different spot?
