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.

Key Features

  • Industry-first SPD 500‑cell Alpha catalytic converters combining ultra‑high flow with green emissions design

  • Full 3″ mandrel bent 304 stainless steel tubing to minimize back pressure and EGTs

  • CNC laser‑cut ½″ thick 304 SS turbo flanges for precision and strength

  • 4″ flex pipe integrated to absorb engine movement and chassis flex

  • TIG & MIG welded construction for superior durability

  • High‑grade V‑band clamps for leak‑free sealing

  • Direct bolt‑on replacement design with NO CEL output, engineered to function as factory downpipe

Benefits

  • Enhanced horsepower and torque thanks to vastly improved exhaust flow

  • Faster turbo spool and reduced turbo lag for immediate throttle response

  • Lower exhaust gas temperatures (EGTs) for improved engine longevity

  • Better fuel mileage under real‑world driving

  • No tuning required—fits straight onto factory turbos

  • Check engine light free operation with ULEV‑compliant Alpha cats

Product Specs

  • Material: 304 stainless steel (pipes and flanges)

  • Tubing diameter: 3″ mandrel‑bent

  • Catalytic converter: SPD Alpha 500‑cell ULEV catalytic converters, USA‑made, rhodium‑enriched

  • Flange thickness: ½″ 304 SS CNC laser‑cut turbo flange

  • Flex section: 4″ stainless steel flex pipe

  • Welding: TIG and MIG methods for maximum structural integrity

  • Finish: Brushed stainless (natural)

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.
