About the product
Upgrade the exhaust flow and performance of your Porsche 911 992 Carrera 3.0L with the Project Gamma Stainless Steel Downpipes, engineered for improved flow, reduced restriction, and a more aggressive exhaust character.
Designed specifically for the 992-generation Porsche 911 Carrera platform, these downpipes feature a precision-machined stainless steel V-band transition and full-size tubing designed to maintain strong exhaust flow from the turbochargers through the downpipe section.
Unlike designs that reduce pipe diameter immediately after the turbo outlet, the Project Gamma downpipes are built with a larger-flowing layout to help minimize restriction and support tuned, higher-performance applications.
Constructed from 304 stainless steel, the system provides excellent heat resistance, corrosion resistance, and durability for both street and performance use.
