Roush Performance 421711 Side Exit Cat-Back Exhaust System

The Roush Performance 421711 Side Exit Cat-Back Exhaust System delivers the iconic Roush aggressive sound while maintaining an OEM-style appearance on your 2011-2014 Ford F-150. This complete exhaust system is engineered to increase horsepower and torque by improving exhaust flow and reducing back pressure, helping your truck reach its full performance potential.

Key Features:

• Fits all 2011-2014 F-150 models with 5.0L V8, 6.2L V8 (including SVT Raptor), and 3.5L EcoBoost engines
• Compatible with all cab and bed configurations (SuperCrew, SuperCab, Regular Cab)
• 3-inch diameter mandrel-bent piping for consistent, unrestricted exhaust flow
• Muffler, inlet, outlet, and Y-pipes constructed from high-grade 409 stainless steel for long-lasting durability
• Dual chrome-flashed 304 stainless steel tips embossed with the ROUSH logo
• Side-exit design with tips exiting behind the passenger-side rear tire
• Canister-style muffler deletes restrictive factory resonator for aggressive, throaty exhaust note
• Single inlet/dual outlet configuration
• Uses factory hanger locations for straightforward installation
• All necessary mounting hardware included

This cat-back system produces a deep, throaty rumble at idle with minimal drone under load, and an aggressive growl under acceleration. The mandrel-bent construction ensures consistent flow throughout the system, unlike crimp-bent exhausts that can cause restrictions. Installation typically takes 2-3 hours with basic hand tools, though the mid-pipe will need to be cut to length based on your specific cab and bed configuration.

Note: 2011-2014 F-150 Platinum and Harley Davidson editions with 6.2L engines require modification to the factory exhaust flange. Roush Performance recommends checking local noise ordinance levels prior to purchase.
