Project Gamma’s catalog at XPH includes intakes, catback exhausts, axle-back systems, midpipes, downpipes, charge pipes, charge coolers, chiller systems, carbon fiber components, upgraded clutches, intake manifolds, and other supporting hardware.
Project Gamma Upgrades for BMW M Cars
BMW performance platforms make up a major part of the Project Gamma lineup.
There are options available for numerous BMW M models, including the G87 M2, G80 M3, G82/G83 M4, F80 M3, F82/F83 M4, F87 M2 Competition, F90 M5, F91/F92/F93 M8, and newer G90/G99 M5, depending on the individual product.
For the S58-powered BMW G80 M3, G82/G83 M4, and G87 M2, Project Gamma offers several different upgrade paths.
Drivers looking for improved airflow can choose from silicone or carbon fiber intake systems, while exhaust options include catback systems, valved axle-back exhausts, midpipes, and other exhaust-flow upgrades.
Project Gamma also offers supporting performance components such as catted downpipes, charge coolers, charge pipes, cooling systems, carbon fiber engine components, and oil cooler protection for select applications.
That allows BMW enthusiasts to build progressively, starting with sound and airflow modifications before moving into cooling, tuning support, or more aggressive performance setups.
Exhaust Upgrades for More Sound and Flow
One of Project Gamma’s strongest categories is its range of exhaust systems.
For BMW applications alone, the lineup includes catback exhausts, axle-back systems, midpipes, resonator-delete solutions, and other exhaust components for multiple generations of M cars.
For the G8X M3 and M4 platform, customers can find options ranging from traditional stainless-steel catback configurations to more aggressive single-exit designs.
Project Gamma exhaust systems are aimed at enthusiasts who want to change the personality of their vehicle while improving exhaust flow. Depending on the application, systems may also retain factory functionality such as OEM exhaust-valve operation.
For customers who have been waiting to give their car a deeper and more aggressive sound, the Fall Sale creates a good opportunity to make that upgrade while select products are discounted.
Intake Systems for BMW, Lamborghini, Audi and More
Project Gamma also offers intake systems designed to increase airflow while bringing more turbo and induction sound into the driving experience.
Available applications include various BMW M2, M3, M4, M5, and M8 models, along with high-performance vehicles such as the Lamborghini Urus, Audi RSQ8, Audi SQ8, Mercedes-AMG GT, and Lamborghini Huracán.
Depending on the vehicle, Project Gamma offers both carbon fiber and silicone intake solutions, giving customers different options depending on budget, appearance, and build goals.
Carbon fiber systems can dramatically change the appearance of the engine bay while also replacing restrictive factory intake paths, while silicone systems can provide a more performance-focused alternative at a lower entry point.
For turbocharged vehicles, upgraded intake systems are particularly popular because they can increase induction sound and support improved airflow as power demands increase.
Cooling Upgrades for Higher-Performance Builds
As boost and power rise, temperature management becomes increasingly important.
Project Gamma addresses this with several cooling-related upgrades, including charge coolers, charge pipes, and chiller systems for different high-performance platforms.
Project Gamma chiller systems are available for applications including the BMW S58, B58, F80/F82/F83 M3 and M4, and F90/F91/F92/F93 M5 and M8, along with universal configurations.
For vehicles that are tuned, driven hard, or frequently exposed to high ambient temperatures, additional cooling capacity can play an important role in maintaining consistent performance.
Cooling upgrades can therefore be especially valuable when paired with increased boost, upgraded turbochargers, ethanol blends, or other modifications that increase engine output.
Project Gamma for Audi and Lamborghini Performance Platforms
Project Gamma is not limited to BMW applications.
The lineup available at XPH also includes performance parts for vehicles such as the Audi RS6, RS7, R8, SQ7, SQ8, Lamborghini Huracán, and Lamborghini Urus.
For Audi RS6 and RS7 owners, available products include performance-oriented components such as catted downpipes, while Audi R8 and Lamborghini Huracán applications include products ranging from performance clutch assemblies and oil catch cans to carbon fiber X-braces and other supporting upgrades.
Project Gamma also offers a full Huracán twin-turbo kit, showing how far the brand’s catalog extends beyond typical bolt-on modifications and into serious high-horsepower builds.
For Lamborghini Urus and compatible Audi platforms, Project Gamma offers components such as carbon fiber intake systems and exhaust upgrades, giving owners of these high-output SUVs additional options for improving both sound and performance.
Mercedes-AMG Performance Upgrades
Mercedes-AMG enthusiasts are also represented in the Project Gamma catalog.
For the Mercedes-AMG GT, GT S, and GT R, Project Gamma offers products including carbon fiber intake systems and high-flow catted downpipes.
These types of upgrades target two of the most important areas on a turbocharged performance platform: getting more air into the engine and helping exhaust gases move more efficiently out of it.
When combined with appropriate supporting modifications and tuning, improved intake and exhaust flow can become part of a much larger performance package.
Supporting Upgrades for High-Horsepower Builds
Project Gamma also caters to enthusiasts moving beyond basic bolt-ons.
The product lineup at XPH includes components such as performance clutches, intake manifolds with port-injection support, charge-cooling systems, and other hardware designed for vehicles operating at substantially higher power levels.
For example, upgraded drivetrain components can become increasingly important as torque rises beyond the limits of factory hardware.
Similarly, port-injection-compatible intake manifolds, improved cooling, and upgraded charge piping can help support builds running more aggressive tuning, ethanol fuels, or upgraded turbocharger systems.
This gives customers the ability to use Project Gamma products at multiple stages of a build rather than limiting the brand to one specific type of modification.
Performance and Carbon Fiber Upgrades in One Catalog
Performance does not always have to come at the expense of appearance.
Project Gamma also produces several carbon fiber components designed to complement its mechanical upgrades.
Depending on the application, the catalog includes components such as:
- Carbon fiber engine covers
- Carbon fiber cooling shrouds
- Carbon fiber strut braces
- Carbon fiber GT-style grilles
- Carbon fiber headlight-delete components
- Carbon fiber intake systems
For enthusiasts building a complete vehicle rather than focusing exclusively on horsepower, these components can help create a more cohesive engine bay and exterior appearance while maintaining the performance-oriented character of the build.
