Ford F-150 Performance Exhaust – Flowmaster Outlaw Series (2021–2026). This direct-fit muffler and over-axle upgrade delivers an aggressive tone and proven performance for 2.7L, 3.5L, and 5.0L non-PowerBoost trucks with factory dual tailpipes.

Constructed from durable 409 stainless steel with 3.0-inch mandrel-bent tubing, this system uses the Outlaw Series muffler for maximum flow and a bold, track-inspired note. It connects directly to the factory dual tailpipes, retains OE hangers, and includes hardware and instructions for an at-home install. Dyno testing showed gains of up to 16 hp and 21 lb-ft at the rear wheels. Replaces only the factory muffler and over-axle pipes while reusing the factory tips. Not for PowerBoost hybrid or OEM active-exhaust models.
