Proposition 65 (Safe Drinking Water and Toxic Enforcement Act of 1986) is a California law that applies to all companies selling products in California. Proposition 65 requires warnings if a product contains any listed chemical present above very low levels that are known to cause cancer, birth defects or other reproductive harm. Proposition 65’s warning standards are among the most stringent in the world. Proposition 65 is not a product safety law, but rather a “right-to-know” law. Businesses are required to provide warnings to comply with Proposition 65. These warnings are required to be in place for all products offered for sale in California.
There are over 800 chemicals on the Proposition 65 list, which is administered by California's Office of Environmental Health Hazard Assessment (OEHHA), a part of the California Environmental Protection Agency. The list includes naturally occurring and man-made chemicals. Proposition 65 warnings can be seen for a wide variety of everyday consumer products, including Automotive Performance products, and warnings can be seen posted throughout California in a variety of establishments such as hotels, restaurants, automobile dealerships/repair shops, and retail stores just to name a few.
To comply with the requirements of Proposition 65, this warning is present on all products sold by MPT.

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.

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.
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.
