Building a performance BMW is about more than adding horsepower. Exhaust flow, intake efficiency, charge-air management, engine calibration, and supporting hardware all play a role in how a modified vehicle performs and sounds.

Active Autowerke has spent more than four decades developing performance products around these areas, with a catalog that covers everything from exhaust systems and mid-pipes to downpipes, charge pipes, software tuning, intake components, and forced-induction upgrades.

At Extreme Power House, the Active Autowerke lineup covers a wide range of BMW platforms, from older E-chassis cars to modern G-chassis models, while also extending into applications such as the Toyota GR Supra and select Porsche models.

A Performance Catalog Built Around BMW

Active Autowerke's product range is particularly extensive for BMW enthusiasts.

The current XPH catalog includes applications for BMW platforms powered by engines such as the N20, N26, N54, N55, B46, B48, B58, S55, S58, S63, and N63, along with products developed for specific M cars and chassis generations.

That range means Active Autowerke can support very different types of builds, whether you're upgrading an older turbocharged BMW, modifying a B58-powered street car, or developing a modern M car.

Active Autowerke Exhaust Systems

Exhaust upgrades are one of the most prominent parts of the Active Autowerke catalog.

XPH carries complete exhaust systems, rear axle-back systems, mid-pipes, X-pipes, equal-length systems, exhaust tips, and supporting exhaust hardware for numerous BMW applications.

Current examples include the G80/G82 M3/M4 Signature Single Mid-Pipe, F80/F82 M3/M4 Signature Exhaust System, F87 M2 Competition Signature Exhaust System, G2X M340i/M440i Valved Rear Axle-Back Exhaust, and X3M/X4M Valved Rear Axle-Back Exhaust.

For enthusiasts who want to modify the sound and flow of their existing exhaust without replacing the entire system, Active Autowerke also offers application-specific mid-pipe and exhaust-section options.

Mid-Pipes for Modern BMW M Cars

Active Autowerke has developed multiple mid-pipe solutions around BMW's modern M platforms.

For the G80/G82 M3/M4, XPH carries the Signature Single Mid-Pipe with the required brace included. The catalog also includes M2 and F8X-specific mid-pipe configurations.

These products allow enthusiasts to target the exhaust section specifically while retaining other portions of their existing setup, depending on the vehicle and selected configuration.

For the G2X platform, Active Autowerke also offers a M340i/M440i MidPipe with Active brace, providing another option for B58-powered BMW owners looking to modify their exhaust system.

Downpipes for Turbocharged BMWs

For turbocharged BMW builds, the downpipe is another major component within the Active Autowerke catalog.

XPH currently carries downpipe applications for several BMW engines and platforms, including:

• B46 230i / 330i / 430i
• N26 F3X 228i / 328i / 428i
• N55 F3X / M235i / F87 M2
• B58-powered BMWs
• S58 F97/F98 X3M/X4M
• S63/N63-powered BMW X5 M, X6 M, X5, X6, 550i, and 650i applications

The catalog also includes a BMW Supra B58 Catted Downpipe designed for applicable F- and G-chassis B58 platforms through the listed model years.

Active Autowerke's lineup includes catted configurations for several applications, giving customers an option beyond conventional uncatted race-oriented downpipes.

B58 Performance Upgrades

The B58 has become one of the most popular BMW engines for aftermarket performance, and Active Autowerke has developed several products around the platform.

XPH carries B58 software tuning for both F-chassis and G-chassis BMWs, including applications such as the:

• M240i
• 340i
• 440i
• M340i
• M440i
• M240i
• 540i
• 640i
• 740i
• X3 M40i

Active Autowerke also offers B58 tuning for the Toyota GR Supra MKV/A90.

This gives B58 owners the ability to approach their build from both the hardware and software side.

ECU Software Tuning

Active Autowerke's software catalog extends well beyond the B58.

The company offers ECU calibration solutions across numerous BMW engines and chassis, with current applications covering older naturally aspirated platforms as well as modern turbocharged vehicles. Active Autowerke describes its software range as including ECU flashes and OBD1 chip-tuning solutions, with BMW remaining a major focus.

At XPH, current software applications include tuning for:

• BMW N20
• BMW N54
• BMW N55
• BMW B46/B48
• BMW B58
• BMW S55
• BMW S63/N63
• BMW M2/M3/M4 platforms
• BMW X5M/X6M
• BMW M550i/M650i/M750i
• Toyota GR Supra

There are also software applications for selected Porsche models, including 991.1 GT3 and 991.2 GT3 RS.

Charge Pipes and Airflow Components

Active Autowerke's catalog also includes supporting airflow hardware.

XPH carries charge pipes for BMW F-chassis applications, including the 335i, 435i, M235i, and M2, as well as an X-Drive charge pipe for X3/X4 and 335i/435i xDrive applications.

The brand also offers performance air filters, including an E9X M3 performance air filter and cleaning kit as well as a drop-in filter for N54-powered E9X 335 models.

These supporting components can be incorporated into broader intake and airflow-focused builds.

Performance Upgrades for BMW M Cars

Active Autowerke's catalog has extensive coverage of BMW's M lineup.

Current XPH applications include products for:

BMW E9X M3

The E9X M3 lineup includes performance air filters, exhaust components, high-flow catalytic-converter upgrades, software tuning, and the Active Autowerke Gen 2 Level 4 supercharger kit.

BMW F8X M3/M4

For the F80 M3 and F82 M4, XPH carries Signature exhaust systems, single and equal-length mid-pipes, rear exhaust tips, chassis braces, software tuning, and supporting components.

BMW F87 M2 Competition

The F87 M2 Competition is supported with dedicated exhaust, mid-pipe, tuning, and chassis-related products.

BMW G8X M2/M3/M4

Modern G8X owners can find Signature mid-pipes, exhaust tips, rear exhaust components, and other Active Autowerke upgrades designed specifically around these platforms.

BMW X3M/X4M

Active Autowerke also produces S58-specific downpipes, Signature mid-pipe options, and valved rear axle-back exhaust systems for the F97/F98 X3M and X4M.

Supporting Hardware

Not every performance modification requires a major system replacement.

Active Autowerke also offers smaller components that can support larger builds, including:

• Exhaust clamps
• Chassis braces
• Replacement filters
• Air filters
• Exhaust tips
• Simon 4 tuning programmer
• Supercharger replacement components
• Supporting exhaust hardware

For example, XPH carries dedicated exhaust clamp sets for both G8X/X3M applications and F8X applications, as well as the Active Autowerke G87 M2 chassis brace.

Active Autowerke for the Toyota GR Supra

Although BMW remains the central focus of the Active Autowerke catalog, the brand also supports the Toyota GR Supra MKV/A90.

XPH carries both a B58 performance software tune and a Signature Catted Downpipe for the Supra, along with the Active Autowerke Supra Performance Cat-Back Exhaust System.

This is particularly relevant for GR Supra owners looking to build around the B58 platform and combine hardware upgrades with ECU calibration.

Performance Software for Porsche

Active Autowerke's software development also extends into selected Porsche applications.

The XPH catalog currently includes performance software for the 991.1 Porsche GT3 from 2013–2016 and 991.2 Porsche GT3 RS models from 2018 onward.

This gives Porsche owners access to Active Autowerke's software expertise beyond its core BMW applications.

Matching Hardware With the Right Platform

One of the advantages of Active Autowerke's catalog is the level of application-specific coverage.

A B58-powered G20 M340i does not necessarily use the same components as an older N55-powered F3X BMW. Likewise, G8X M cars, F8X M cars, X3M/X4M models, and older E-chassis platforms each have their own hardware requirements.

When selecting an Active Autowerke product, customers should verify the exact vehicle, chassis, engine, model year, drivetrain, and product configuration listed on the individual product page.

This is particularly important for components such as downpipes, charge pipes, exhaust systems, and software tuning, where fitment and compatibility can be highly platform-specific.

Build Your Active Autowerke Setup

Active Autowerke offers products that can be used at different stages of a performance build.

A relatively simple setup might start with an air filter or exhaust component. A more involved turbocharged build could combine a downpipe, charge pipe, exhaust system, and ECU calibration. Higher-output projects can go significantly further with components such as the E9X M3 supercharger system.

The current XPH catalog therefore spans everything from individual supporting components to major performance systems.
