This comprehensive warranty protection reflects MRT's confidence in premium materials, manufacturing processes, and American-made craftsmanship.
Performance Benefits and Sound Characteristics
Substantial Power and Torque Gains
The complete cat-back design with straight-through muffler configuration and 2.5-inch mandrel-bent tubing dramatically reduces exhaust restriction compared to the factory system. By optimizing flow from the catalytic converter all the way to the outlet, this system allows exhaust gases to exit with maximum efficiency, significantly reducing backpressure.
The result is a performance rating of 9 out of 10, delivering noticeable improvements in horsepower, torque, throttle response, and overall engine breathing. Whether you're towing trailers, hauling cargo in the bed, or climbing steep off-road grades, the enhanced power delivery provides measurable real-world benefits.
Commanding Exhaust Presence
- Idle: Loud, aggressive presence that commands attention
- Cruising: Constant performance sound that maintains character
- Acceleration: Lively attitude with enhanced bite and growl
- Wide Open Throttle: Full muscle truck roar with deep, powerful tone
- Drone Level: Exceptionally low (2/10) for such an aggressive system
The King of the Hill cat-back delivers the loudest, most aggressive exhaust experience available for the Gladiator JT while maintaining remarkable cabin comfort with minimal drone. This careful acoustic engineering ensures you enjoy maximum performance sound without the constant resonance that makes long drives fatiguing.
Premium Construction and Engineering
T304 Stainless Steel Throughout
The entire King of the Hill cat-back system is constructed from premium T304 stainless steel, providing superior corrosion resistance against mud, water, salt, and extreme temperature fluctuations. This professional-grade material ensures your exhaust maintains its appearance and performance through years of demanding off-road use and all-weather conditions.
Every component—from the catalytic converter connection to the turndown outlet—is fabricated from T304 stainless steel, ensuring consistent quality and durability throughout the entire system. No cheaper materials or compromises are used anywhere in the construction.
Precision Mandrel-Bent Tubing
The 2.5-inch diameter tubing is precision mandrel-bent, maintaining consistent internal diameter through all bends and curves. Unlike inferior crush-bent designs that crimp and restrict flow, mandrel bending preserves maximum exhaust flow efficiency while ensuring structural integrity.
This manufacturing process creates smooth, unrestricted exhaust gas flow throughout the entire system, maximizing performance gains while reducing the turbulence that creates unwanted drone. The result is a cat-back system that delivers both maximum power and refined acoustic characteristics.
Turndown Outlet for Off-Road Durability
The 2.5-inch turndown outlet is positioned for optimal ground clearance and protection from trail obstacles. This configuration eliminates the weak points created by traditional exhaust tips extending behind the bumper, providing a robust, damage-resistant exit point that withstands serious off-road use.
The turndown design also prevents exhaust gases from depositing soot on the bumper or tailgate, maintaining a cleaner appearance compared to side-exit or traditional tip configurations
How does it sound? MRT King of the Hill Cat-Back gives an aggressive, Get Noticed exhaust tone that is present at all times.
Is there drone or resonance? Some managed drone.
What if I step on it? Wide-open throttle brings out a more lively attitude with more exhaust sound, bite and a deeper growl.
