Product Description

The ROUSH 421711 is a cat-back side exit exhaust system for the 2011-2014 Ford F-150 across all three engine configurations - the 3.5L EcoBoost V6, 5.0L V8, and 6.2L V8 (including the SVT Raptor). Unlike the rear-exit 421248, this system routes the dual 4-inch chrome-flashed tips to exit behind the passenger-side rear tire, giving the truck a more integrated, factory-like profile while still delivering the full ROUSH exhaust experience. ROUSH achieves its signature sound on this system by deleting the restrictive factory resonator and replacing it with a canister-style muffler - producing a deep, aggressive exhaust note without the unwanted in-cockpit boom or resonance that plagues some aftermarket systems.

The system uses 3-inch mandrel-bent 409 stainless steel piping from the muffler to the tips to maintain consistent flow throughout with no crimp-related restrictions. Both tips are 304 stainless steel with chrome-flash coating and ROUSH logo embossing. The kit installs using factory hanger locations with no modifications required on standard trim trucks. Note: 6.2L Platinum and Harley-Davidson Edition models require factory flange modification. Compatible with ROUSH cold air intake kits and ECU flash tunes. Backed by ROUSH's 3-Year Limited Warranty.
