Stainless Works 2017 F-150 Raptor 3.5L 3in Downpipe High-Flow Cats Factory Connection

If you're looking to get more out of your 2017-2020 Ford Raptor's 3.5L EcoBoost engine, this 3-inch downpipe from Stainless Works is a solid choice. It's designed to replace the factory turbo adapter and restrictive stock catalytic converters, opening up the exhaust path for better airflow and more power. This is a common upgrade for Raptor owners who want to hear more from their twin-turbo V6 and feel a noticeable difference in throttle response.

This downpipe is constructed from 304 stainless steel, which is well-known for its resistance to corrosion, especially important for exhaust components that see a lot of road salt and moisture. Each tube is CNC mandrel bent, meaning the bends are smooth and consistent throughout, which helps maintain exhaust gas velocity and prevent turbulence. The entire assembly is TIG welded for strong, durable joints that can handle the heat and vibration of daily driving. It features high-flow catalytic converters that are less restrictive than the factory units, helping you meet emissions standards in most areas while still improving performance. The mill finish gives it a clean, utilitarian look.

This kit is designed as a direct replacement for the factory downpipe and includes O2 bungs for your factory sensors. It's proudly made in the USA and comes with a lifetime warranty from Stainless Works, reflecting their confidence in the build quality. Please note that this part is not CARB approved and cannot be shipped to California.
