The Quadratec® Difference
Catalog #: 77608.805

Inspired by consumer feedback out on the trails by people who also use their Jeep as everyday drivers, the DynoMax® QuietCrawler™ Performance Exhaust System was specifically designed to provide high clearance for rock crawling, and quiet acoustics for everyday driving. This DynoMax system utilizes a straight-through, polished UltraFlo™ Stainless Steel Muffler plus a Race Bullet Muffler to allow for high flow and pull heat away from the engine while reducing the tone in the cab compared to more common rock crawler designed, performance systems.
