Single - 2.5" Cat-Back System - Ultra Flo™ Polished Muffler

“THE ORIGINAL” STAINLESS STEEL “ROCKCRAWLER” CAT-BACK SYSTEM
DynoMax® was first to market back in 2007 when the JK Wrangler hit the dirt with a true, hard-core based system built and engineered for those Jeep owners that were interested in a system that would give them great performance as well as clearance. While imitated and impersonated by our competitors, this original design from DynoMax has been tried, true, and trail tested by the best of them. Engineered strictly for your Wranglers performance in engine efficiency and ground clearance.


DynoMax® Ultra Flo™ SS Polished performance mufflers are constructed of stainless steel for lifelong durability and completely polished for show-quality shine. The unrestricted, straight-through design is dyno proven to flow up to 2,000 SCFM and support up to 1,900 horsepower. Each muffler uses our exclusive Continuous Roving Fiberglass (CRF) Technology to absorb unwanted interior resonance while maintaining a deep performance tone. The 'Pure Unadulterated POWER' of DynoMax® Ultra Flo™ SS Polished mufflers are backed by a Limited Lifetime Warranty and exclusive 90-Day Performance & Sound Guarantee™. All Dynomax® Performance Exhaust Systems bolt on for easy installation. Your vehicle's complete exhaust can be quickly and easily customized with an emissions-legal premium performance system from Dynomax®.
