Project Gamma High-Flow Downpipes
Project Gamma downpipes feature a high-flow 3-inch construction with precision CNC-machined stainless-steel V-band transitions for proper fitment and unrestricted exhaust flow.
Unlike competing downpipes that reduce in diameter near the turbo outlets, our downpipes maintain a full 3-inch diameter throughout the system for maximum flow and performance.
-
Handcrafted from 304 stainless steel
-
Full 3-inch high-flow construction
-
Precision CNC-machined connections
-
Improved turbo response and reduced turbo lag
-
More aggressive exhaust sound
-
Designed for tuned and high-performance applications
-
Potential gains of approximately 50+ horsepower and 60+ lb-ft of torque with proper calibration
Actual performance gains may vary depending on fuel quality, vehicle condition, supporting modifications, and tune selection.
Project Gamma Silicone Intake System and Filters
Our intake system is manufactured from four-layer reinforced silicone with an oil-resistant inner lining and precision aluminum connectors for improved airflow, strength, and durability.
The increased internal diameter and smoother airflow path provide:
-
Improved airflow and engine response
-
Faster turbo spool
-
Enhanced throttle response and acceleration
-
Aggressive turbo and induction sound
-
OEM-plus fitment and engine-bay appearance
-
Improved resistance to collapsing under high boost
Please select your preferred intake and filter colors before checkout.
ECU Unlock and Tuning
This package includes the ECU unlock service required to flash compatible aftermarket tuning software.
Customers must contact Project Gamma before bringing in or shipping their ECUs to receive instructions and confirm compatibility.
After the ECUs are unlocked, customers may select their preferred tuning platform:
-
Bootmod3
-
MHD
Both platforms allow the vehicle to be properly calibrated for the upgraded downpipes and intake system while optimizing power delivery, throttle response, and drivability.
An ENET cable and compatible device may be required to flash or manage the tune. Contact Project Gamma if you need help confirming cable or device compatibility.
Stage 2 Recommendation
For Stage 2 applications, two-step-colder spark plugs gapped to approximately 0.022 inches are recommended unless your tuner specifies a different gap.
Fitment and Installation
-
Designed for BMW M5 and M8 F90/F91/F92/F93 platforms
-
Direct bolt-on installation
-
No cutting or permanent vehicle modifications required
-
Includes the necessary installation hardware

Professional installation is strongly recommended
Ceramic-Coating Option
Some product images may show ceramic-coated downpipes.
For improved thermal protection and reduced engine-bay heat, select the Ceramic Coating option before checkout. If ceramic coating is not selected, the downpipes will be supplied in a polished stainless-steel finish.
Important Notes
-
Contact Project Gamma before bringing in or shipping your ECUs.
