Modern BMW performance platforms offer an enormous amount of aftermarket potential. Once modifications begin, however, improving one area of the car can quickly expose limitations somewhere else.

More airflow may create a need for better cooling. Increased turbocharger output may require improved intake and charge-side hardware. More engine power can make exhaust flow and drivetrain support increasingly important.

Mastery of Art & Design, better known as MAD, has developed a broad range of performance components around these requirements, with a catalog covering intake systems, air filters, downpipes, midpipes, exhaust systems, heat exchangers, charge-side components, skid plates, drivetrain hardware, and other supporting upgrades.

At Extreme Power House, the MAD lineup is particularly focused on modern BMW platforms, including B58, B48, S55, S58, N54, N55, N20/N26, and BMW M applications, with additional products for the Toyota GR Supra.

A Complete Approach to BMW Performance

A performance vehicle is a system made up of interconnected components.

The intake controls how air reaches the turbocharger. The turbocharger compresses that air. The intercooling system manages charge temperatures. The exhaust removes combustion gases. The ECU determines how the engine uses all of those components.

MAD's catalog addresses several of these areas, allowing enthusiasts to upgrade individual components according to the needs of their vehicle.

Rather than being limited to one particular type of modification, the current XPH catalog includes everything from relatively simple high-flow filters and intakes to downpipes, exhaust systems, cooling upgrades, and drivetrain-related hardware.

MAD Intake Systems

Airflow is one of the first areas many turbocharged BMW owners address.

MAD offers several types of intake solutions, including cold-air intakes, front-mount intakes, silicone intake components, and high-flow filters.

The exact design varies by platform.

For example, the current MAD range includes a BMW G8X cold-air intake with heat shield, a G8X S58 front-facing silicone intake, and a G8X S58 high-flow air filter. There are also dedicated intake systems for the F90 M5/F9X platform and B58-powered BMWs.

These products give owners different approaches to improving the intake side of the engine depending on the existing setup and intended build.

Cold-Air Intake Systems

A cold-air intake is designed to improve the path through which air enters the engine while controlling the intake environment.

MAD offers application-specific cold-air intake systems for platforms including the G8X M3/M4, F90 M5, F9X vehicles, G30 B58, and G0X B58 applications.

For enthusiasts who want a more substantial intake upgrade, complete systems can provide a different solution than simply replacing the factory filter.

Front-Facing Intakes

MAD also produces front-facing intake configurations for selected BMW platforms.

The current catalog includes G2X B58 and G8X S58 front-facing silicone intake options.

These products are designed around their respective engine platforms, so the correct application should always be verified before ordering.

High-Flow Air Filters

Not every build requires a complete intake replacement.

For owners looking for a simpler airflow modification, MAD offers high-flow replacement filters for several BMW applications.

Current listings include high-flow filters for the G8X S58, along with other BMW platforms.

A filter can therefore be used as an individual modification or as part of a larger intake system upgrade.

MAD Downpipes

For turbocharged BMWs, the downpipe is another major component of the exhaust path.

MAD produces application-specific catted and catless downpipes, along with different configurations designed around specific BMW engines and chassis.

The catalog includes downpipe applications for platforms such as:

• BMW G8X S58
• BMW F9X S58
• BMW F9X
• BMW B58
• Other BMW turbocharged applications

The F9X lineup, for example, includes primary downpipes, primary catted downpipes, secondary downpipes, S58 downpipes, and Fatboy downpipe configurations.

Catted vs. Catless

MAD offers both catted and catless configurations across applicable platforms.

The appropriate option depends on the intended use of the vehicle, local emissions requirements, and the rest of the exhaust and tuning setup.

A catted configuration incorporates catalytic converters, while a catless configuration removes that restriction entirely.

Customers should verify local regulations before selecting an emissions-related exhaust component.

MAD Midpipes

The midpipe is another area where BMW owners can modify exhaust flow and sound without necessarily replacing the entire exhaust system.

MAD offers multiple midpipe configurations for modern BMW platforms, including:

• Single midpipes
• Resonated single midpipes
• Non-resonated single midpipes
• Resonated H-pipes
• Titanium single midpipes
• Larger-diameter performance midpipes

The current G8X/S58 catalog includes several variations, including a 4-inch Fatboy single midpipe, resonated single midpipes, resonated H-pipes, and a resonated titanium single midpipe.

This variety allows enthusiasts to approach the exhaust system according to their desired sound, configuration, and overall build.

Axle-Back and Cat-Back Exhaust Systems

MAD's exhaust lineup extends beyond midpipes.

The XPH catalog includes axle-back and full cat-back exhaust systems for various BMW applications.

Current examples include:

• BMW G87 M2 axle-back exhaust
• BMW G0X B58 cat-back exhaust
• BMW F90 M5 full cat-back exhaust
• BMW G8X S58 axle-back exhaust

These systems allow enthusiasts to modify the rear section of the exhaust independently or replace a larger portion of the factory system.

G8X M3 & M4 Performance

The G80/G81 M3 and G82/G83 M4 are among the most prominent platforms in the modern BMW aftermarket, and MAD offers a substantial selection of parts for them.

Current products include:

• S58 front-facing silicone intakes
• High-flow air filters
• Cold-air intake systems
• Heat exchangers
• Resonated downpipes
• Single midpipes
• Resonated H-pipes
• Titanium single midpipes
• Axle-back exhausts
• Other supporting hardware

This allows a G8X owner to approach the build from several different directions rather than being limited to a single product category.

F9X M5 & M8 Performance

MAD also offers extensive coverage for the F90 M5 and F9X M8/X5M/X6M platforms.

Available products include:

• Carbon-fiber cold-air intake systems
• Front-mount silicone intakes
• High-flow filters
• Primary downpipes
• Catted primary downpipes
• Secondary downpipes
• S58-specific downpipes
• Cat-back exhaust systems
• Skid plates
• Other supporting hardware

The F90 catalog also includes a dedicated carbon-fiber cold-air intake and full cat-back exhaust system.

This makes MAD particularly relevant to owners who want to improve both airflow and exhaust performance on BMW's high-output M platforms.

B58 Performance Upgrades

The B58 remains one of the most widely modified BMW engines, and MAD has developed multiple components around it.

Current catalog examples include:

• B58 cold-air intake systems
• B58 front-facing silicone intakes
• B58 cat-back exhausts
• Supporting airflow components

Applications include BMW G30 and G0X B58 vehicles as well as other B58-powered BMW platforms.

Because the B58 is also used in the Toyota GR Supra, the platform has become particularly popular among enthusiasts looking to build progressively higher-output turbocharged vehicles.

Toyota GR Supra Applications

MAD's development extends beyond BMW to the Toyota GR Supra.

The Supra shares its B58 engine architecture with BMW, creating significant overlap in the type of performance hardware that can be developed for the platform.

MAD's catalog includes Supra-focused performance components alongside its BMW lineup.

As always, Supra owners should verify the exact generation, model year, engine configuration, and product-specific fitment before ordering.

Cooling Upgrades

As engine output increases, thermal management becomes increasingly important.

MAD offers cooling components designed to support performance-oriented BMW builds, including the G8X S58 High Performance Heat Exchanger.

The heat exchanger is part of the vehicle's cooling system and is particularly relevant when a modified engine is generating more heat than the factory configuration.

Cooling upgrades should be selected according to the vehicle's actual usage. A daily-driven street car and a vehicle regularly subjected to repeated high-load operation can place very different demands on the cooling system.

Skid Plates and Protective Hardware

Performance modifications aren't limited to horsepower-producing components.

MAD also develops hardware intended to protect and support the vehicle.

The current catalog includes skid plates for platforms such as the F90 M5 and F9X/S58 applications.

A skid plate can help protect components underneath the vehicle from road debris and impacts, making it a practical addition for vehicles that are driven regularly on roads with uneven surfaces.

Drivetrain and Supporting Components

Higher-output builds can also create additional demands on components beyond the engine.

MAD's broader product lineup includes supporting hardware such as billet transmission pans and other vehicle-specific components. XPH's MAD catalog has expanded beyond the traditional intake-and-exhaust categories into additional hardware designed around modified BMW platforms.

These types of products can become increasingly relevant as an enthusiast's build progresses.

Building Around the S55 and S58

BMW's S55 and S58 engines are both heavily represented in the aftermarket, but their hardware requirements are not interchangeable.

MAD produces application-specific components for each platform.

The S58 lineup includes products for the G8X M3/M4 and F9X vehicles, while MAD's broader catalog also covers S55-equipped BMW applications.

This distinction is important when selecting parts. An intake, downpipe, or midpipe designed around one engine should not be assumed to fit another simply because both engines are BMW M powerplants.

Choosing the Right MAD Product

With a broad catalog available, selecting the right component begins with the vehicle rather than the product category.

Before ordering, confirm:

• Chassis: F30, G20, G80, F90, F9X, G87, and other BMW chassis can require completely different components.
• Engine: B58, S58, S55, B48, N55, N54, and other engines have different hardware requirements.
• Model year: Product fitment can change during a vehicle generation.
• Drivetrain: RWD and xDrive configurations may use different components.
• Exhaust configuration: Some products are designed around specific factory or aftermarket exhaust arrangements.
• Existing modifications: Intake, downpipe, turbocharger, exhaust, and cooling modifications can affect what should be installed next.

The individual product listing should always be treated as the final authority for fitment.

MAD for Street and Performance Builds

One of the practical aspects of the MAD catalog is that its products can be used across different levels of modification.

A relatively stock BMW might begin with a high-flow filter or intake.

An enthusiast focused on sound could move to a midpipe or axle-back exhaust.

A tuned turbocharged car may benefit from additional airflow and cooling hardware.

A higher-output build may incorporate downpipes, larger intake systems, upgraded cooling, exhaust components, and additional supporting hardware.

The correct combination depends on the vehicle and the intended use rather than simply installing every available component.
