Product Description

The MagnaFlow 17122 Off-Road Pro Series Cat-Back Exhaust System is purpose-built for the 2000-2006 Jeep Wrangler TJ (2-door), supporting the 2.4L I4, 2.5L I4, and 4.0L I6 engines across the Sport, Rubicon, Sahara, X, SE, and 65th Anniversary Edition trims. Unlike traditional cat-back systems, the Off-Road Pro Series routes exhaust with a turndown exit before the rear axle - a critical design choice that eliminates tip overhang, maximizes departure angle, and protects the exhaust outlet from trail obstacles. The undercarriage-hugging pipe routing also contributes to improved ground clearance, making this system an ideal upgrade for stock and modified TJs alike.

Built from 100% stainless steel with 2.5-inch mandrel-bent tubing and a compact 5x5x14-inch straight-through muffler, the 17122 is engineered for both maximum flow and minimal weight. The result is a dyno-proven increase in horsepower and torque with a Very Aggressive exterior exhaust tone and an Aggressive interior note - unmistakably louder and more performance-oriented than MagnaFlow's street-oriented systems. The system is fully compatible with lifted, long-travel, air-bagged, and highly modified suspension setups, making it one of the most versatile bolt-on exhaust options available for the TJ platform.

Installation is bolt-on using 3D-scanned direct-fit design - no cutting or custom fabrication required. The 3.0-inch satin stainless clamp-on turndown tip installs without welding. Note that some owners with heavily modified TJs may need to source a slightly longer factory-style isolator hanger (approximately 1.5-2 inches longer than OEM) for proper alignment. This system is recommended for off-road use only and is not available to California residents. All components are backed by MagnaFlow's limited lifetime warranty.
