24–25 Ford Raptor 3.5L SPD Performance 35FR24SS GEN4 Alpha Catted Downpipes
This GEN4 Alpha Catted Downpipe set is engineered specifically for the 2024–2025 Ford F‑150 Raptor with the 3.5 L EcoBoost engine. Ford’s redesign in 2024 relocated the turbochargers directly onto the heads, eliminating exhaust manifolds—and this product adapts perfectly to that change. Equipped with industry‑first 500‑cell Alpha catalysts and full 3″ mandrel‑bent 304 stainless steel tubing, it delivers dramatic improvements in airflow, throttle response, fuel economy, turbo spool, and exhaust gas temperature control, all without triggering a check engine light. CNC‑laser‑cut ½″ stainless turbo flanges, TIG/MIG welds, and a 4″ flex section ensure durability and precise fit. Catalytic converters are domestically made and suitable for race use. Designed as a direct replacement—no tuning required.

Install Difficulty Level
The install process is straightforward and smooth. Experienced users report that mounting is easier than OEM due to better access and precise alignment—components slide into place, and all bolt locations line up perfectly. No tuning is needed, and everything bolts directly onto the turbo assembly. Overall, this is a user‑friendly swap designed to make installation quick and painless.
Vehicle Fitment
This downpipe set fits 2024 and 2025 Ford F‑150 Raptor equipped with the 3.5 L EcoBoost V‑6 engine, specifically versions that feature the GEN4 direct‑bolt turbo configuration. Confirmed to adapt to the new turbo‑to‑head layout introduced for Raptor models in those years.
