MRT designed this King of the Hill axle back system for the Ford Bronco enthusiast who wants the loudest, most aggressive sound and wants to customize with accessories that make a difference. MRT believes that every Bronco aftermarket part should be purposeful so, we removed the Bronco factory single exit exhaust and replaced it with a MRT dual exit exhaust with standard polished tips. The result? an elevated Bronco sound with no question that something's different about this SUV. As auto enthusiasts, we love to hear a deep, rumble and purr when we're driving and this system doesn't disappoint with the best sounding exhaust note in every element of driving. Fortunately, MRT engineers are experts at designing exhausts without drone or resonance so you always have full time FUN with this King of the Hill dual tip axle back.

So, what's this dual tip axle-back system sound like? At start up, sporty sound with a very deep rumble that gets your attention. City driving has a definite growl with no boom or resonance and when you step on it, you have some attitude that says I am coming!! Highway driving is fun with an extra, low, whir to come along on the ride.

The design of the MRT King of the Hill Bronco axle-back follows MRT premium exhaust designs made from premium, corrosion resistant, 2.5" T304 Stainless Steel and featuring two 3.5" stainless steel tips in bring polish or black ops finish. We love the straight tube design so it opens up the exhaust sound, opens up the flow and opens up more opportunities for fun! If you're looking for this sound in single tip or dual tip option, check out MRT Part # 90R234 (single) and MRT Part # 90R238 (dual).

MRT also offers a Trail rated Bronco exhaust series for the customer who wants a more mellow performance sound that grows to full-on performance at wide open throttle. We have 2 options for you: turn down tip (MRT Part # 90R232) and single exit polished or black tip (MRT Part # 90R236).

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 # 8K110

    Bronco king of the hill axle back dual tip exhaust
    Ez install in like 15 min, quality exhaust well made and great looking. Great throaty sound throughout the drive. Never seems to be too loud even at start up. I'm very happy with MRT stuff and have MRT exhaust on my Fiesta ST also.

    It's so hard to listen to a video clip and decide what exhaust you want and sounds best. Look no more. This Black Ops King of the Hill exhaust sounds great and looks great.
