When Full-Race set out to create a premium downpipe for the 2017–2020 EcoBoost 3.5L, the goal wasn’t just to offer another option. We wanted something that worked exactly the way our turbo systems were designed to. That meant partnering directly with SPD to build a version made specifically for the Full-Race billet turbo adapters, delivering the best possible flow and compatibility.
The result is a custom SPD Alpha Catted Downpipe that uses separate turbo adapter flanges to create a perfect port match from the turbo outlet into the start of the downpipe. This design removes the step or restriction found in smaller one-piece flanges, creating a smooth, continuous exhaust path that reduces backpressure and improves turbo response.
By keeping the billet adapter interface, this downpipe integrates seamlessly with Full-Race Power Packs and Garrett Powermax Stage 2 Turbo upgrades. The combination ensures consistent fitment across installs and delivers real, measurable performance gains.
Each system is built from 3-inch mandrel-bent 304 stainless steel and includes high-quality catalytic converters, precision v-band connections, and all necessary hardware for a direct bolt-on installation. The result is a durable, emissions-compliant system that improves flow and response.
Built by SPD and designed exclusively for Full-Race, this downpipe was created for EcoBoost owners who care about every detail in the pursuit of performance.
