SPD Performance Alpha Catted Down-Pipes for 2021-2026 Ford F-150 3.5L PowerBoost. Designed to enhance exhaust flow and reduce back pressure while improving turbo response and fuel efficiency. Factory downpipes create restrictions by reducing diameter from 5.5 inches to 5 inches causing higher backpressure. These Alpha Cats feature 3-inch mandrel bent tubing to improve performance. 500 Cell ultra high flow rhodium loaded catalytic converters maintain emissions standards without triggering check engine lights. 304 stainless steel construction with CNC laser cut 1/2-inch thick flanges, TIG and MIG welded for durability. Includes 4-inch flex pipe to absorb engine movement and chassis flex shock. Improves throttle response, mileage, and overall performance while reducing turbo lag and exhaust temperatures. Direct factory replacement requiring no custom tuning. EPA approved federal catalytic converters, not legal for California shipment.
