MAD G87 M2 Axle Back Exhaust

Unleash the raw power and dynamic sound of your BMW G87 M2 with the MAD Valved Sport Exhaust System. Engineered for enthusiasts who demand excellence, this exhaust system is designed to elevate your M2’s performance and auditory presence, delivering a driving experience that’s both thrilling and refined.


Exhilarating Sound: The MAD Valved Sport Exhaust System transforms the M2’s exhaust note, providing a deeper, more aggressive tone that truly complements the car’s performance pedigree. Whether you’re accelerating down the straightaway or cruising through town, this system ensures your M2 sounds as formidable as it feels.

Performance Boost: Featuring larger diameter piping and optimized flow paths, this exhaust system reduces backpressure and enhances exhaust gas evacuation, resulting in tangible performance gains. Enjoy improved horsepower and torque, giving your M2 an extra edge on the road or track.

Adaptive Sound Control: Equipped with valved technology, the MAD Sport Exhaust System allows you to control the exhaust sound profile. Closed valves offer a quieter, more refined sound for daily driving, while open valves deliver a full-bodied, aggressive exhaust note that’s perfect for spirited driving. The system seamlessly integrates with the M2’s drive modes, allowing for on-the-fly adjustments.

Premium Construction: Constructed from high-quality T304 stainless steel, this exhaust system is built to last. The TIG welding ensures superior strength and durability, while the brush-finished surface provides a sleek, premium look that complements the M2’s aesthetic.

Enhanced Aesthetics: The system features quad 4-inch (100mm) exhaust tips that perfectly fill the factory rear valence, adding a touch of visual aggression to match the enhanced sound. These clamp-on tips are easily adjustable, allowing for a customized look.

Features:

Diameter: Optimized larger diameter piping for improved flow
Tips: Quad 4-inch (100mm) clamp-on tips
Material: 100% T304 stainless steel construction
Weight Reduction: Lighter than the stock exhaust system, improving overall vehicle dynamics

Is this compatible with cars that has OPF? And shot you and email very keen to know if we can run this catless DP without a tune without resulting in power loss due to low back pressure?

If you leave your factory midpipe and opf intact you can just cut and bolt this one without any issues.

There are no power losses from adding a catless downpipe without a tune but, you won't see a significant gain either until it's tuned.

Shout out to Anthony from MAD-US for the help on this Axleback. Completely changes up the sound the car and looks absolutely phenomenal. As it sits, the car currently has the MAD Catless Downpipes, the MAD Front Mount Intakes, the MAD Axleback and not shown in the video is the sound difference that the SST Valve Controller made. I'll be looking to post a video sometime in the next week or so to showcase the difference in sound. It sounded great with just the axleback, sounds even MEANER with the valves being able to open fully. The tone is nice and deep with plenty of crackles and pops without any added raspiness. It makes the intake whooshes sound even louder which is always a great. With valves closed, the sound is extremely similar to stock which provides comfort when cruising. Single midpipe coming soon but still debating between resonated and non-resonated. Quality and fitment is absolutely flawless, you can't go wrong with anything from the team over at MAD!

Pro Tip: Disable the Active Sound Design module via Bimmercode to ensure you don't get any crappy fake noise inside the cabin.

No offense meant here or anything, but your description of your exhaust here is almost verbatim from Dinan's description of their G87 exhaust. What's up wit dat?


The G87 M2 excels in nearly every aspect compared to its precursor, but the prevailing concern among enthusiasts lies in its sound quality. Similar to its predecessor, the S55 in the f87, the S58 in the current generation still leaves room for improvement. While the stock sounds are a step up from the previous generation, they still have an excess of raspiness that fails to convey the refined aggression inherent to the brand's signature performance models. MAD remedies this shortcoming with a valved axle back exhaust system that delivers a deeper, more impactful note, and adds a level of amplification beyond the stock version. When paired with the optional single midpipe, it yields an even louder, smoother, and fuller sound.

To achieve the desired sound volume and tone befitting the G87 M2, we increased the tubing size to 76mm (from the stock's 70mm), which reduces back pressure and allows a freer flow throughout the system. The larger piping diverges into multiple paths as it approaches the vehicle's rear, the choice of which is determined by the factory exhaust valves that are retained.

When the valves are closed, flow is directed into the MAD muffler, and exits through the two inner tips. This restricts noise during low-speed driving and produces a more subdued yet deeper sound. When the valves are open during high-load conditions, most gases bypass the muffler entirely for a near-straight pipe design, achieving maximum aural enjoyment. This harmonious balance satisfies a range of tastes and offers civility or passionate aggression as the situation demands. MAD has determined this combination to be appropriate for the brand's signature performance models that cater to discerning enthusiasts who want the best in all scenarios.

Visually, MAD's G87 M2 exhaust is meticulously constructed entirely from T304 stainless steel and TIG welded for superior visual appeal and color. The entire system is brush finished for a perfect look straight out of the box. The attention to detail isn't limited to the unseen parts once the exhaust is installed; it extends to the exhaust tips as well. MAD's exhaust includes substantial quad 4.5-inch (114mm) clamp-on exhaust tips. Despite their large size on paper, the tips seamlessly integrate and fill the factory cut-outs, achieving the OEM+ look with an added touch of audible attitude.

Features:

Connects to Factory Midpipe (Cutting required) or MAD Single Midpipe (No Cutting required)
Maximum gains of +5 HP and +5 lb-ft of torque
Pleasingly louder, sportier sound
Drone abatement technologies reduce cabin resonance
4.5-inch (114mm) tips
Reuses stock exhaust valve actuators, and the operation of exhaust valve is unchanged so the exhaust tone can be adjusted via the M-drive settings
Includes extended valve harness
Computer-controlled exhaust valves are retained and limit noise during low-speed driving, and open fully during high-load conditions
100% 304 Stainless Steel construction
Factory-like fitment with included mounting hardware

That's funny I used our G80 m4 Description to make this, which we made a long time ago. I guess Dinan is using chat gpt to write their descriptions or they copied ours

Edit this was a screw up on our end. this descritpion should of never been used.

I guess that's why it's called "artificial" intelligence?

[Sleeper]

Are there any in-car or drive-by videos with the axleback and midpipe (and stock DP's)?

[Sleeper]

Alright, rolled the dice. Resonated midpipe and axleback ordered through mike@x-ph.com. I think ETA is July so a bit of a wait, but sale pricing made it worth it (on top of already lower starting price point).

I’m always a “you get what you pay for” person, but I just can’t understand the price points for some of the other options. The MAD pricing is $1500 for the axleback with carbon tips and $1100 for a resonated midpipe, putting a total catback cost of around $2600. With some axlebacks alone starting north of $3k (so $4-5k with a midpipe), I just don’t see the value. These are noisemakers, adding next to 0% performance increase. Unless this thing rusts after a year and fits like crap, I think it’ll be a winner.

Ordered mine too, but I did the Dinan midpipe. Same thinking... it's a midpipe. Plus it's Dinan so I know it's quality. Finish is top notch.

Does this fit with Dinan midpipe without additional cutting? If that's the case, I think I'll go with the MAD axleback

MAD said as long as Dinan uses the same cut points as MAD, the 2 will work together since all 4 parts (both midpipes & exhausts) work with OEM midpipes or the exhaust. Since I am installing all of this together, I can even double check cutpoints before doing the cuts. Measure twice, cut once & all...

Per dinans instructions they use the Middle cut point like our midpipe.

Scheduled release date was 7/18. Has the exhaust been released? What's the ETA for those of us who have placed our orders?

Thanks!
