Product description
Unlock the full performance potential of your BMW M5 or M8 (F90/F91/F92/F93) with Project Gamma’s complete downpipe, intake, and ECU tuning package. Designed for serious performance gains, our high-flow downpipes are paired with premium silicone intake systems and your choice of Bootmod3 or MHD ECU tuning — giving you the flexibility to tune your vehicle on the platform you prefer for maximum results.
This all-in-one performance bundle is engineered to improve exhaust flow, increase airflow, and unleash significant horsepower and torque gains — all while adding aggressive induction sound and a clean engine-bay aesthetic.
Package Highlights
🔥 Project Gamma High-Flow Downpipes
Project Gamma downpipes for the M5 and M8 models feature a high-flow 3” construction with precision CNC-machined stainless steel v-band transitions for optimal exhaust flow. Unlike competitors that constrict near the turbos, our downpipes maintain a full 3D diameter throughout for maximum flow and performance gains when tuned.
-
Handcrafted from 304 stainless steel
-
Designed for tuning and performance builds
-
Gains up to ~50+ HP and ~60+ lb-ft torque with proper calibration
-
Improved turbo response, reduced lag, and enhanced sound
🌀 Project Gamma Silicone Intake System & Filters
Our intake system is engineered using 4-layer reinforced silicone with an oil-resistant inner lining and precision aluminum connectors that ensure improved airflow and durability. The larger internal diameter and smooth airflow path deliver:
-
Increased horsepower and response
-
Faster turbo spool
-
Enhanced throttle feel and acceleration
-
Aggressive induction sound and OEM-plus fitment
The reinforced silicone construction also prevents collapsing under high boost pressures and high-flow filter setups.
Note: Please select your preferred intake color and filter color at checkout.
⚙️ ECU Tuning Options (Choose at Checkout)
Take full advantage of your new hardware by selecting one of the supported ECU tuning platforms:
✔ Bootmod3
✔ MHD
Both platforms allow for professional calibrations that unlock performance while ensuring smooth power delivery and reliability. You will need an ENET cable and a compatible device to flash your vehicle — email us with any questions regarding cable compatibility.
🔧 Stage 2 Recommendation:
2-step colder spark plugs gapped to 0.22 are recommended for Stage 2 applications.

Our workshop technicians cross-reference manufacturer technical schematics, platform codes (such as S58, B58, S63TU), and your vehicle registration or VIN before placing the order.
