🚀 Elevate your F-150’s roar and style—because average is not an option.
The ROUSH 421711 Cat-Back Exhaust system is engineered for 2011-2014 F-150 5.0L, 6.2L, and 3.5L models, delivering enhanced airflow with 3" mandrel-bent stainless steel piping and a canister-style muffler. Crafted from durable 409 and 304 stainless steel, it offers superior corrosion resistance and a polished OEM look with side-exit tips. This exhaust system removes the factory resonator to produce the signature aggressive ROUSH sound while fitting all cab and bed configurations, requiring minimal modification for select editions.
