MBRP S5278BLK Armor BLK 3-Inch Dual Turndown Axle-Back for 2022-2026 Ford F-150

Vehicle Fitment

• 2022-2026 Ford F-150 Raptor (3.5L EcoBoost HO V6, 4WD)
• 2023-2026 Ford F-150 Raptor R (5.2L Supercharged V8, 4WD)

Fitment Notes

• 3.5L EcoBoost HO and 5.2L Supercharged engines only - does not fit standard F-150 trims or the previous-generation 2017-2021 Raptor
• This is an axle-back system - replaces the exhaust section aft of the rear axle only; does not include front pipe, mid-pipe, or muffler
• Dual rear turndown exit configuration routes exhaust downward at the rear for increased underbody clearance - ideal for off-road use and trail articulation
• Bolt-on installation using factory OEM hangers - no cutting or welding required
• High-heat black powder coating is best suited for off-road and dry-climate use - prolonged exposure to heavy road salt may affect the coating over time
• This system does not replace, modify, or affect any emissions control equipment

Features

• Constructed from T304 stainless steel with a high-heat engineered black coating - combines the corrosion resistance of T304 with a stealthy, blacked-out finish that matches the Raptor's aggressive aesthetic
• Smooth mandrel-bent 3-inch tubing maximizes exhaust flow and reduces backpressure for improved throttle response
• Dual rear turndown exit with laser-welded high-clearance tails - increases ground clearance and protects the exhaust exit during serious off-road articulation
• Street Profile sound tuning produces a deeper, more commanding exhaust note under throttle without harsh drone on extended highway runs
• Bolt-on design uses factory OEM mounting points - no modifications required beyond the rear axle
• Black coating is specifically engineered to withstand the extreme heat cycles an exhaust system is exposed to during performance and off-road use
• MBRP 1-Year Warranty included on black coating

Product Description

The MBRP S5278BLK is an Armor BLK axle-back exhaust system built exclusively for the 2022-2026 Ford F-150 Raptor with the 3.5L EcoBoost HO engine and the 2023-2026 Raptor R with the 5.2L Supercharged V8. Sharing the same laser-welded, high-clearance dual rear turndown construction as the T304 S5278304, this system adds an engineered high-heat black powder coating over the T304 stainless tubing for a stealthy, murdered-out aesthetic that complements the Raptor's purpose-built off-road identity. The dual turndown exit configuration routes exhaust gases downward at the rear bumper, meaningfully increasing underbody clearance for technical trail use and rock crawling where obstacle contact is a real concern.

Street Profile sound tuning delivers a deeper, more assertive exhaust note under acceleration while keeping things composed on long highway drives. Installation is fully bolt-on using factory OEM hangers - no cutting, welding, or modification of the factory exhaust beyond the rear axle is required. This system replaces only the axle-back section and does not affect the muffler, mid-pipe, or any emissions equipment. Backed by MBRP's 1-Year Warranty on the black coating.
