MRT King of the Hill JL Axle Back Exhaust (90R140) - 2018+ Jeep Wrangler JL 3.6L and 2.0L
Take your 2018+ Jeep Wrangler JL to the next level with the MRT King of the Hill Axle Back Exhaust. Designed for drivers who want maximum sound and presence, this system delivers an aggressive, always-on exhaust tone that stands out both on the street and on the trail. With its bold dual tip design and commanding sound, your Wrangler will make a statement wherever you go.
Constructed from premium T304 stainless steel, this system features 2.5 inch mandrel-bent tubing and a straight-through design to maximize exhaust flow and reduce back pressure. This allows your engine to breathe more efficiently, resulting in improved throttle response and noticeable performance gains. Dual 4 inch double-wall stainless steel tips provide a clean, aggressive rear appearance, with an optional Black Ops matte finish available for a stealthy look.
As one of the loudest options in the MRT Wrangler lineup, the King of the Hill system delivers a strong, aggressive tone while maintaining manageable drone levels for daily driving. Designed for both 2-door and 4-door JL models, including 3.6L V6 and 2.0L powertrains, this system offers a direct bolt-on installation with included hardware. Engineered and manufactured in the USA, it is backed by a limited lifetime warranty.
