Built Around BMW Performance
Mastery of Art & Design, better known as MAD, has developed a strong presence in the BMW aftermarket by focusing on practical, vehicle-specific performance upgrades.
The current MAD lineup at Extreme Power House covers a wide variety of BMW platforms, including B46, B48, B58, N20, N55, S55, S58, and S63-powered vehicles, with applications ranging from F-chassis models to the latest G-series BMWs. MAD also offers products for the Toyota GR Supra, particularly B48- and B58-powered applications.
This platform-focused approach makes it easier for enthusiasts to find upgrades designed specifically for their vehicle.
Increase Airflow with MAD Intakes
One of the most popular ways to begin modifying a turbocharged BMW is by improving the intake system.
MAD offers a variety of high-flow air intakes, front-mount intakes, silicone intake systems, turbo inlet upgrades, and replacement filters. These products are available for numerous BMW applications, including M2, M3, M4, M5, M8, M340i, M440i, 540i, and X3M/X4M platforms.
For B58 and S58 owners in particular, MAD provides multiple intake configurations designed around the specific requirements of these engines.
Upgrade Your BMW's Exhaust Flow
MAD also has an extensive selection of performance exhaust components, giving enthusiasts plenty of ways to change both exhaust flow and sound.
The lineup includes downpipes, single midpipes, H-pipes, axle-back exhausts, and complete cat-back systems. Depending on the vehicle, MAD offers both resonated and non-resonated configurations, along with catted and catless downpipe options.
MAD's exhaust products cover popular BMW performance platforms such as the F87 M2 Competition, F80/F82 M3/M4, G80/G82/G83 M3/M4, G87 M2, F90 M5, G90/G99 M5, X3M, X4M, and other B58-powered BMWs.
Toyota GR Supra owners can also find MAD intake and exhaust-related upgrades designed specifically for their platform.
Charge Pipes, Turbo Inlets & Supporting Hardware
As power levels increase, supporting modifications become increasingly important.
MAD offers upgraded charge pipes and turbo inlet components for several BMW turbocharged engines, including B58, N55, S55, and S58 applications.
These components can complement intake and exhaust upgrades as part of a larger bolt-on setup, helping enthusiasts build their vehicles progressively rather than replacing every component at once.
Cooling and Drivetrain Upgrades
MAD's catalog goes beyond airflow and exhaust components.
Enthusiasts can also find heat exchangers, intercooler-related upgrades, billet transmission pans, and other supporting hardware designed for demanding performance applications.
For BMW owners running increased power, maintaining appropriate charge-air and drivetrain temperatures can be an important part of building a consistent and dependable setup.
Exterior and Practical Performance Hardware
MAD also produces a range of practical components designed to complement performance builds.
The lineup includes skid plates, wheel spacers, DRL LED modules, exhaust valve controllers, and other vehicle-specific accessories.
These products allow enthusiasts to address areas beyond engine performance while continuing to build a cohesive, purpose-driven vehicle.
