The Injen Technology exhaust system for the Jeep Gladiator features full 3 mandrel bent 304 stainless steel tubing that provides optimal pipe routing for maximum flow and additional clearance for extreme off - road use. That 3 piping flows directly into our Injen oval muffler that was designed specifically for the new Jeep powerplants. Our Jeep specific muffler is shallow in height to provide increased ground clearance, all while having the correct interior volume and design to tame the exhaust note of the mighty Jeep Gladiator. Delivering a smooth, deep tone that is distinct to the Injen exhaust line, this system provides you with all dyno - proven performance you crave and the sound enhancements that you demand.
