The Ford Bronco offers endless customization options, and MRT has taken full advantage by designing the King of the Hill G.O.A.T. (Greatest Over Axle Turndown) Exhaust to give your Bronco a bold, aggressive sound and enhanced performance. This system is the definitive choice 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 premium, corrosion-resistant 2.5" T304 stainless steel, ensuring maximum durability in the harshest environments. Engineered for the serious enthusiast, the King of the HIll G.O.A.T. Series is tucked high to optimize ground clearance and departure angles. Specifically, this system is designed to accommodate aftermarket rear sway bars and maximize rear-end clearance, ensuring your performance upgrades never compete for space. The straight-through design allows both the 2.3L and 2.7L EcoBoost engines to breathe freely, improving overall flow.

At startup, the King of the Hill G.O.A.T. Series 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. Under hard acceleration, the exhaust roars to life, providing an aggressive performance sound worthy of the Bronco’s 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.

A standout feature of this system is its compact, subtle turndown tip, designed to keep the focus on performance while avoiding obstructions. This layout also provides the necessary clearance for upgrading to the Bronco Raptor tow hitch, making this exhaust ideal for drivers who demand maximum towing capacity and off-road capability.

For those looking for a deeper, more refined exhaust note, check out the Elite Series G.O.A.T. Exhaust, which includes a precision engineered muffler for a more refined performance sound without the drone.

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. Series. For the full MRT effect, add MRT Ford Bronco Hood Struts (MRT Part # 80K110) to eliminate the factory prop rod with a clean, no-drill installation.

Hear the Difference
How does it sound? The MRT Bronco Elite Series G.O.A.T. (#90R230) has an aggressive exhaust note that demands attention.

Is there drone or resonance? The drone is minimal and well-managed for an over-axle design.

What if I step on it? Wide-open throttle brings out an extreme exhaust roar that screams "take no prisoners."

    The growl is perfect
    The MRT KOH G.O.A.T. Series Exhaust is a fantastic addition to my Bronco. Installation was a breeze (for my husband 🤣), taking less than 20 minutes with no modifications needed. The aggressive growl is perfect—attention-grabbing yet allows me to enjoy my music without interference. Love the additional clearance that this product provides for those who love to wheel. Highly recommend this upgr

    10 out of 10! MRT delivered on this one!!
    Where do I start? How easy install was, the profile the exhaust gave my Bronco or the beefy tone it delivered...I was able to have the stock muffler off of my 23 Heritage and the new MRT "King of the Hill, G.O.A.T" exhaust installed in under an hour. They've made a perfect piece of metal here! We're talking 2.5" T304 stainless steel which means it's going to withstand corrosion and keep up with

    Sporty rumble with the best clearance
    The King of The Hill G.O.A.T series exhaust is hands down the best I've had installed on my Bronco. Not only is it priced well, it is made really well. It also provides the best clearance which was extremely important to me when out on the trails. I highly recommend this exhaust for those wanting the best clearance and for those wanting a deeper rumble!

    Best Possible Choice
    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.
