Legend Catback w/X-Pipe

The Legend Catback w/X-Pipe by Stainless Works is a premium exhaust system engineered for 2011–2021 Jeep Grand Cherokee models equipped with the Mopar Gen III Hemi engine. This cat-back exhaust replaces the restrictive factory system from the catalytic converter rearward, delivering improved airflow, responsive throttle feel, and a more aggressive exhaust note without sacrificing reliability or emissions compliance. Built for drivers who demand both performance and durability, this system transforms the driving experience while maintaining factory fitment integrity.

Constructed from high-grade stainless steel in a natural (polished) finish, the Legend Catback features a 3-inch diameter tubing with a factory-style X-Pipe crossover design that balances exhaust scavenging and low-end torque delivery. The X-Pipe configuration reduces turbulence at the merge point and improves cylinder-to-cylinder scavenging, resulting in more consistent power across the RPM range compared to traditional H-pipe designs. Dual rear exit outlets provide a symmetrical aesthetic and optimal exit velocity, while the full stainless construction resists corrosion and thermal degradation over extended ownership—essential for vehicles subjected to salt exposure or aggressive driving conditions.

Enthusiasts and weekend warriors with Gen III Hemi-powered Grand Cherokees will appreciate the bolt-on simplicity and immediate feedback this system delivers. Installation requires no modifications to the vehicle frame or suspension, and the system integrates cleanly with factory mounting points. Whether used for off-road trail driving, highway cruising, or spirited back-road runs, the Legend Catback w/X-Pipe provides measurable improvements in exhaust flow and engine responsiveness. Weighing 76.96 lbs, it represents a negligible mass penalty while offering substantial gains in drivability and acoustic character.
