Express Delivery SPD 2024-2025 Ford F-150 & Raptor 3.5L EcoBoost Alpha Catted Downpipes

Ford’s newest 3.5L EcoBoost engines are stronger and smarter than ever — but the factory downpipes still hold them back. The stock system reduces the primary cat diameter from 5.5″ to 5″, creating higher backpressure and elevated exhaust gas temperatures under load.

SPD’s Alpha Catted Downpipes eliminate that restriction with 3″ mandrel-bent 304 stainless tubing, CNC-cut ½” flanges, and ultra high-flow catalytic converters that free up exhaust flow, sharpen throttle response, and reduce turbo lag — all while keeping your truck emissions-compliant and check-engine-light free.

At the heart of these downpipes is SPD’s Alpha 500-cell catalytic converter, a breakthrough design that outflows standard 400-cell performance cats by +90% while still meeting green emissions standards. Each converter is extra-loaded with Rhodium, a platinum-based alloy that helps reduce NOx emissions and meet modern EPA requirements — something no other high-flow cat can claim.

Whether you’re driving a 2024–2025 F-150 or Raptor, these downpipes strike the perfect balance between performance, durability, and compliance — delivering cooler exhaust temps, faster spool, and smoother power, with no tuning or guesswork required.

Application List

• 2024-2025 Ford F-150 3.5L EcoBoost
• 2024-2025 Ford Raptor 3.5L EcoBoost

• Ultra High-Flow Alpha Cats: 500-cell converters outflow previous designs by +90% while staying emissions-compliant and CEL-free.
• 3” 304 Stainless Construction: Mandrel-bent tubing resists heat, corrosion, and cracking for long-term durability.
• CNC Laser-Cut ½” Turbo Flanges: Precision-cut for a perfect seal and leak-free performance under boost.
• 4” Flex Pipe: Absorbs engine movement and prevents stress cracks or vibration issues.
• Direct Bolt-On Replacement: Installs using factory turbo connections. No cutting, welding, or tuning required.
• Improved Flow & Spool: Reduces backpressure and turbo lag for quicker response and cooler EGTs.
• Made in the USA: Designed, welded, and built domestically for quality you can trust.
• No CEL (Check Engine Light): Designed and tested to run clean — no tuning adjustments or O2 spacers necessary.

SPD uses EPA-approved federal catalytic converters, but you are responsible for verifying legality with your state and county laws.

Note: On 2024–2025 Raptor models, Ford eliminated the traditional exhaust manifolds — the turbos bolt directly to the heads, further optimizing flow and response.
