SPD Performance Alpha Catted Down-Pipes; Ceramic +400 Cell EPA (23-25 F-150 Raptor R)Find parts that fit my vehicle

We are proud to release our 2023-2025 Ford 5.2L Raptor R Alpha Catted Downpipes. Our Industry first Alpha Cats provide ultra high flow while meeting green emission standards. Factory Raptor R downpipes are very restrictive with 2.25" front tubes and 2.5" post cat tubes. This causes very high back pressure and hot EGTs. Factory cats are burning up with cat temp as hot as 1950 degrees. 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 cat temperatures. Our flanges are CNC laser cut 304ss flanges and 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 downpipes do not require custom tuning and can be used as a factory downpipe 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 400cell 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.

On all SPD Performance 304 stainless catted downpipes, you get:
Increase in performance
Reduces Cat Temperatures
Better fuel mileage
Direct manifold bolt-on design
NO CEL - Ultra High Flow 400Cell catalytic converters that do not cause check engine lights
304 Stainless Steel 3" mandrel bent tubing
High grade v-band clamp for a solid seal and no leaks
