ABOUT THE PRODUCT
Transform your BMW M5 or M8 with Project Gamma’s high-flow downpipes and ECU tuning package, designed for maximum performance, sound, and efficiency. Choose between Bootmod3 or MHD tuning at checkout — giving you the flexibility to tune your vehicle on the platform you prefer.
This package includes our premium primary and secondary downpipes engineered to significantly improve exhaust flow, turbo response, and overall power delivery when paired with tuning — all at a better value than purchasing components separately. Project Gamma
🚀 What’s Included
Project Gamma M5 / M8 Downpipes
Project Gamma downpipes for the M5 and M8 models utilize 3” high-flow construction with precision CNC-machined stainless steel v-band to pipe transitions. Our full 3D design maintains true diameter throughout the system, unlike competitors that neck down near the turbos — resulting in superior airflow and performance gains when tuned. Project Gamma
-
Constructed from 304 stainless steel for durability and corrosion resistance
-
Designed for high output and tuning applications
-
Expect gains of approximately 50+ HP and 60+ lb-ft torque when properly tuned
⚙️ Tuning Options
Select your preferred ECU tuning platform:
✔ Bootmod3
✔ MHD
Both options allow you to properly calibrate your vehicle for downpipes and unlock optimized performance. An ENET cable and compatible laptop or device are required to flash the tune. Contact us for any questions about cable compatibility. Project Gamma
🔧 Stage 2 Recommendation:
2-step colder spark plugs gapped to 0.22 are recommended for Stage 2 applications.
