We are proud to release our 2021-2024 Ford 5.0L Coyote Alpha Catted Y Pipes. Our Industry first Alpha Cats provide ultra high flow while meeting green emission standards. Factory F-150 downpipes are very restrictive. With SPD Alpha ultra high flow cats and larger 3″ diameter mandrel bent tubing, you will improve throttle response, mileage and overall performance while reducing back pressure and exhaust temperatures. We TIG & MIG weld the downpipes for strength and durability. We designed in a 4″ flex pipe to absorb shock from engine movement and chassis flex. Our catted y pipe do not require custom tuning and can be used as a factory y pipe replacement. Our catalytic convertors are made in the USA and are designed to be used in racing applications.
SPD Alpha Cats
SPD Alpha Cats are next generation ultra high flow green emissions catalytic convertors and are truly an industry first. We needed a catalytic convertor that would have high flow and green emissions. Every catalytic convertor that we tested in the industry either had green emissions or high flow but not both. SPD Alpha Cat is a 500cell catalytic convertor and will out flow our previous 400cell performance cats by +90%. They are extra loaded with Rhodium, which is a platinum based alloy that is required in a catalytic convertor to reduce NOX in the exhaust to meet the new emission standards.
