MagnaFlow 17120 Off Road Pro Series Stainless Cat-Back Exhaust System

The MagnaFlow 17120 Off Road Pro Series Cat-Back Exhaust System is a performance-engineered, all-stainless steel exhaust upgrade built for demanding off-road use. Developed with extensive 3D scanning technology, this system delivers a direct-fit, bolt-on installation while producing a very aggressive exterior and aggressive interior exhaust note — MagnaFlow's signature deep, throaty tone under throttle.

The cat-back design replaces all exhaust components from the outlet of the catalytic converter rearward, featuring 2.5-inch diameter mandrel-bent main piping that flows through a single straight-through muffler before exiting via a turndown before the rear axle. The pre-axle turndown exit improves departure angles and reduces overall system weight — ideal for highly modified suspension setups including lifted, lowered, long-travel, and air-bagged configurations.

Key Features:

• 2.5-inch mandrel-bent stainless steel main piping for unrestricted exhaust flow
• Single straight-through perforated-core muffler with no baffles or chambers to restrict airflow
• Turndown-before-axle exit design for improved departure angles and compatibility with modified suspension systems
• 3-inch satin clamp-on single wall turndown cut-edge tip
• 100% stainless steel construction for corrosion resistance and long-term durability
• Weight-optimized, low-profile design hugs the undercarriage for improved ground clearance
• Emissions-legal cat-back configuration — catalytic converter remains in place
• Produced using advanced CNC precision robotic manufacturing techniques
• Includes all necessary clamps, hangers, and hardware for installation
• Backed by MagnaFlow's limited lifetime warranty

The MagnaFlow 17120 is dyno-tested and proven through extensive off-road use, eliminating the need for custom fabrication with true bolt-on fitment. Whether the goal is improved performance, a more aggressive sound profile, or enhanced ground clearance for extreme trail use, this Off Road Pro Series system is engineered to deliver.
