Exhaust Kit for Ford F-250 (2016-2018) 6.2L

High-Flow Dual Muffler-Back Exhaust Kit for 2016-2018 Ford F-250 (P473 / P558)

What it Does: The Dual Muffler-Back Exhaust Kit replaces the restrictive factory chambered silencer on the 2016-2018 Ford F-250 to reduce exhaust backpressure, improve scavenging, and deliver an aggressive deep exhaust tone.

The Stock Ford F-250 Exhaust Restriction

The OEM exhaust assembly on the 6.2L Boss V8 is engineered primarily for cabin noise suppression rather than flow efficiency. Factory mufflers feature restrictive internal chambers, perforated baffles, and necked-down crush bends that choke exhaust velocity post-catalytic converter. Under continuous heavy towing or high-load operating cycles, this restricted path causes unwanted thermal retention and elevated backpressure that hampers engine volumetric efficiency.

The Engineering Solution

This system replaces the stock unit downstream of the catalytic converter with smooth, mandrel-bent 2.5-inch aluminized steel tailpipes paired with a genuine two-chamber Flowmaster Super 44 muffler. The single 3.0-inch inlet splits into dual 2.5-inch outlets, maintaining optimal exhaust gas velocity and scavenged cylinder evacuation. The dual multi-piece tailpipes route parallel to the frame rails, engineered specifically to preserve factory receiver hitch clearances and standard spare tire stowage under full suspension articulation.

What's Included

• 1 Flowmaster Super 44 muffler (single 3" inlet, dual 2.5" outlets)
• 2 aluminized mandrel-bent multi-piece 2.5" tail pipes (slip-together)
• 8 muffler clamps
• 1 larger exhaust clamp
• 4 rubber-insulated hangers
• 2 black powder-coated 3.5" round x 18" weld-on exhaust tips

Frequently Asked Questions & Fitment Warnings

Does this fit the P473 / P558 F-250?

Yes, this is a fit for the 2016-2018 Ford F-250 equipped with the 6.2L Boss engine. Excludes 6.7L Power Stroke diesel models and any gas configurations equipped from the factory with a dual-inlet muffler assembly.

Is this exhaust kit a direct bolt-on installation?

No, this is a universal-fit builder kit requiring slip-fit assembly, potential pipe trimming or fabrication by an experienced installer, and welding for the included exhaust tips.
