Product description
Project Gamma downpipes for the BMW M3 and M4 (G80/G82) are available as a complete performance package that includes high-flow downpipes, FEMTO ECU unlock, and customer-preferred ECU tuning. This bundle is designed to deliver maximum airflow, power, and reliability while offering exceptional value compared to purchasing each component separately.
When paired with proper tuning, Project Gamma downpipes provide significant horsepower and torque gains, improved turbo response, and enhanced overall drivability — making this one of the most effective upgrades available for the G80/G82 platform.
Project Gamma G80/G82 Downpipes
Engineered specifically for the BMW M3/M4 (G80/G82), Project Gamma downpipes feature a 3.5-inch high-flow construction with a precision CNC-machined stainless steel v-band to pipe transition for optimal fitment and exhaust flow.
Unlike many competitors that reduce diameter near the turbo outlets, our downpipes maintain a true full 3D design all the way through the final inches, delivering superior airflow and performance. When tuned, gains of up to 50 horsepower and 60 lb-ft of torque can be achieved.
-
Full 3.5” diameter design
-
Handcrafted from 304 stainless steel
-
Extreme rust and heat resistance
-
Optimized for tuned and high-performance applications

PRE-PURCHASE & SHIPPING FAQ
How does the order-in process work?
We verify live supplier inventory and issue a comprehensive written quote covering the part, current AUD pricing, GST, and tailored freight to your address (or free Stepney collection). Once you review and approve the quote and vehicle fitment is confirmed, your order is secured directly with our manufacturer allocation.

Typical delivery is 1 to 2 weeks for air freight sourced directly from verified European and international manufacturers. Active consignment tracking is maintained throughout transit until parts arrive at our Stepney workshop for collection, workshop installation, or dispatch to your door.
Can I pick up or have parts installed locally?
Yes. Free local collection is available from our Stepney workshop facility in Adelaide. We also offer professional in-house fitting, alignment, and calibration by European platform technicians. Simply select "Supply and fit at Stepney" when submitting your enquiry.
What happens if fitment is uncertain?
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. If there are model-year variations, aftermarket modifications, or clearance concerns, our team confirms compatibility with you and the supplier prior to commitment.
