The BMW G90 and G99 M5 represent the next generation of M performance, combining the incredible capabilities of the twin-turbocharged S68 V8 with cutting-edge hybrid technology. While the performance is undeniable, many enthusiasts agree on one thing—the factory exhaust leaves plenty of the V8's character hidden.

That's why we're excited to introduce the MAD BMW G90/G99 M5 H-Pipe Midpipe, engineered to unlock a deeper, richer exhaust note while maintaining the refinement expected from a modern M car.

Designed specifically for the latest M5 platform, the MAD H-Pipe delivers the authentic V8 sound enthusiasts have been waiting for.

Let the S68 Sound Like a V8

From the factory, the G90 M5's exhaust system prioritizes comfort and noise reduction. The result is an exhaust note that feels restrained, especially considering what's under the hood.

The MAD H-Pipe Midpipe transforms the personality of the S68 by allowing both exhaust banks to communicate through a precision-engineered balance section.

Instead of simply making the car louder, the H-pipe enhances the quality of the sound, producing:

• A deeper exhaust tone
• Fuller low-frequency rumble
• More aggressive acceleration sound
• A smoother, more natural V8 character

The result is an exhaust note that sounds more like a high-performance V8 should, without sacrificing everyday comfort.

Why an H-Pipe?

Every exhaust crossover has its own personality.

Rather than combining both exhaust banks into a single pipe, the classic H-pipe design maintains the dual-exhaust architecture while allowing pressure to equalize between both sides.

This creates several benefits:

• Richer low-end exhaust tone
• Stronger classic V8 rumble
• Balanced exhaust pulses
• Smooth sound throughout the RPM range
• Minimal rasp compared to more aggressive crossover designs

For drivers who appreciate a refined yet muscular exhaust note, the H-pipe remains one of the most popular choices.

Performance Without Compromise

One of the biggest goals during development was improving the sound without negatively affecting everyday drivability.

The MAD H-Pipe was carefully engineered to provide:

• Virtually zero drone during highway cruising
• Increased exhaust presence under acceleration
• Smooth transitions throughout the rev range
• Comfortable daily driving characteristics

Whether you're commuting during the week or enjoying spirited weekend drives, the exhaust remains refined when you want it to be and aggressive when you step on the throttle.

Premium Construction

Like every MAD exhaust product, quality begins with the materials.

The G90/G99 M5 H-Pipe Midpipe is constructed from premium T304 stainless steel, offering exceptional durability, corrosion resistance, and long-term reliability.

Every component is designed specifically for the S68-powered platform to ensure precise fitment and years of dependable performance.

Designed Around Your Exhaust Setup

The MAD H-Pipe offers excellent flexibility for both factory and aftermarket configurations.

It is fully compatible with:

• The factory BMW axle-back exhaust
• The MAD G90/G99 M5 Axle-Back Exhaust

When paired with the MAD Axle-Back, installation is completely bolt-on with no tuning required.

Owners retaining the factory axle-back should note that a small amount of cutting is required during installation.

The Perfect Balance of Sound and Refinement

Not every exhaust upgrade needs to be the loudest option available. For many enthusiasts, the goal is achieving a deeper, more authentic exhaust note that complements the S68 rather than overpowering it.

The new MAD G90/G99 M5 H-Pipe Midpipe does exactly that—delivering a fuller V8 soundtrack, refined highway manners, premium construction, and OEM-quality fitment in one complete package.

If you've been waiting for an exhaust upgrade that enhances the character of BMW's newest M5 without introducing unwanted drone or harshness, this is the solution you've been looking for.
