{"product_id":"fdp50f21ss","title":"SPD Performance Alpha Catted Y Pipe - 2021-2026 F150 5.0L","description":"\u003cp\u003eFactory 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. TIG \u0026amp; MIG weld the downpipes for strength and durability and are designed in a 4\" flex pipe to absorb shock from engine movement and chassis flex. SPD's catted y pipe does not require custom tuning and can be used as a factory y pipe replacement. Their catalytic convertors are made in the USA and are designed to be used in racing applications.\u003c\/p\u003e\n\u003cp\u003eSPD needed a catalytic convertor that would have high flow and green emissions. Every catalytic convertor that they tested in the industry either had green emissions or high flow but not both. SPD Alpha Cat is a 6\" 400cell catalytic convertor and will out flow their 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does the diameter of the cat matter? \u003c\/strong\u003eAlpha catalytic convertors have a diameter of 6\". They have a substrate surface area of 28\" for the exhaust to flow through.
