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 serve a purpose. We removed the Bronco factory single-exit exhaust and replaced it with an 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 that deep, rumble and purr when we're driving. 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 a King of the Hill dual tip axle back.
So, what does a dual tip axle-back system sound like? At start up, you hear a sporty sound with a deep rumble that grabs your attention. City driving has a definite growl with no boom or resonance, and when you step on it, you have attitude that says I am coming!! Highway driving is also fun with an extra, low, whir that comes along on the ride.
The design of the MRT King of the Hill Bronco axle-back follows MRT performance exhaust designs made from premium, corrosion-resistant, 2.5" T304 Stainless Steel and featuring two 3.5" stainless steel tips in bright polish or black ops finish. We love the straight tube design that opens the exhaust sound, improves exhaust gas flow and provides more opportunities for fun! MRT offers King of the Hill exhaust systems in
Single Tip # 90R234 and
Dual Tip # 90R238 options.
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! For off-road enthusiasts and ORV trail rides, install the MRT ORV
flag mount for great visibility and to protect your Bronco from flag rubbing or chafing.
