The Ford Bronco offers endless customization options, and MRT has taken full advantage by designing the G.O.A.T. (Greatest Over Axle Turndown) King Of The Hill Exhaust to give your Bronco a bold, aggressive sound and enhanced performance. This system is perfect for drivers who want an untamed, raw exhaust note that matches the Bronco’s legendary off-road prowess.

This over-axle turndown exhaust is handcrafted from high-quality, premium, corrosion-resistant 2.5" T304 stainless steel, ensuring maximum durability and performance in all conditions. The exhaust is tucked up high, optimizing ground clearance and departure angles, which is perfect for navigating tough off-road terrain. The straight-through design allows the engine to breathe freely, enhancing performance for both the 2.3L and 2.7L EcoBoost engines.

At startup, the G.O.A.T. King Of The Hill exhaust delivers a noticeable rumble, giving your Bronco a strong presence without being overbearing. As you hit the road or trail, the sound grows into a tough, commanding tone, with no annoying drone. On hard acceleration, the exhaust roars to life, providing an aggressive performance sound worthy of the Bronco’s iconic reputation. This system lets you truly Hear the Difference and Feel the Performance—it’s built for those who want to make a statement, both visually and audibly.

One of the standout features of the King Of The Hill Exhaust is its compact, subtle turndown tip, designed to keep the focus on performance while avoiding any obstructions. This system not only sounds great but also leaves room for upgrading to the Bronco Raptor tow hitch, which is spec'd for heavier loads, making this exhaust ideal for drivers who demand both performance and towing capacity.

For those looking for a deeper, more refined exhaust note, check out the Trail Rated G.O.A.T. Exhaust, which includes a Trail Rated muffler for a more mellow sound. Explore both options and find the perfect fit for your Bronco.

If you're an ORV trail enthusiast, you can also add the MRT ORV Flag Mount Kit to complement your setup, and enjoy an exclusive discount when purchased together with the G.O.A.T. King Of The Hill Exhaust.Also, for the full MRT effect, add MRT Ford Bronco Hood Struts to eliminate that prop rod without drilling holes in your vehicle! Check out MRT Part # 80K110.

    Quality metal, great sound, high clearance and reasonable price. I have tested a few different exhausts on my Bronco. This one blew them all away in every category. After install, I drove over 1,000 miles without turning on the radio. I just enjoyed the 2.3L flowing freely.
